The Benro Series 3 is probably the sturdiest of that bunch. Most Series 3 tripods use a minimum diameter 32mm top tube. Plus that tripod has 3-section legs with twist type leg locks.... both good things.

You didn't specify which Gitzo Traveler you are looking at, but the Series 2 is the "heaviest duty" they offer in that series and it uses 4-section legs to be more compact... not ideal for stability... more sections mean smaller diameter bottom sections, in order for them to nest inside each other. In order to be as small as possible, the Traveler also uses a two section center column, which probably isn't great for stability (see below, regarding center columns, in general).

The Induro Stealth is a Series 2, like the Gitzo and smaller diameter than the Benro... but it uses 3-section legs, which is good.

All three of these tripods are around 52" or 53" tall when the center column isn't used. This is important because ideally, for best stability, you want to use center columns as little as possible... preferably not at all. How tall are you? Or, more importantly, have you measured your eyeline from the floor while standing? That can tell you how tall tripod you need to be comfortable.... and whether or not you'll need to extend the center column. Raising the center column of those tripods appears to add 10 or 11" height (plus the height of whatever head you put on it and the distance from the base of your camera to it's viewfinder eyeport).

I use three Gitzo tripods.... all of which are Series 3. Two of them have 3-section legs and no center column at all, but are plenty tall for my 5' 9". I use with full size gimbal head on one and ballhead, often with gimbal adapter, on the other. Both raise the eyeport of my camera considerably above the tripod's max extension height. I also use leveling platforms on both of those, which add slightly more than 1" to the height. Overall, they are well above my eyeline so I have no need for a center column.

My third Gitzo is set up differently for other purposes. It's an extra tall model, has 4-section legs and a rapid center column installed (optional). At full extension it's close to 7 or 8 feet! I very rarely need to use it so high (and only do so very carefully), seldom extend the bottom-most leg section or raise the center column at all. In fact, one of my main uses of the center column is reversing it to hang a camera below the tripod, for low angle shots. As a result, it's nearly as steady as the other two tripods, there's not as much compromise of stability like there would be if I needed to use the center column and fully extend the legs all the time, to have adequate work height.

I don't know how tall tripod you need... But most people would need to fully extend those tripods legs, as well as raise the center column, to put the camera at a comfortable work height. I can't help but wonder if any of them will be substantially more stable that what you have now.

RRS makes very good stuff. But... in my opinion... priced between $380 and $565 depending upon the exact model, that BH-40 is extremely over-priced. It's just a freakin' ballhead! Medium duty, 18 lb. rating. Between 15 lb. and 25 lb. I found 55 ballheads listed at B&H with similar features. The RRS dominate the most expensive. Many others are available for a lot less, that do exactly the same thing! https://www.bhphotovideo.com/c/search?sts=ma&Ns=p_PRICE_2%7c1&sortType=default&fct=fct_support-weight_1470%7c15-lb%2bfct_support-weight_1470%7c16-lb%2bfct_support-weight_1470%7c17-lb%2bfct_support-weight_1470%7c18-lb%2bfct_support-weight_1470%7c20-lb%2bfct_support-weight_1470%7c22-lb%2bfct_support-weight_1470%7c24-lb%2bfct_support-weight_1470%7c25-lb%2bfct_support-weight_1470%7c26-lb%2bfct_quick-release-system_7375%7carca%2bfct_head-type_1544%7cball-heads&srtclk=sort&ipp=72&N=0&Ntt=ballhead After all, a $25,000 Ford does the same thing as a $250,000 Ferrari. But, hey, it's your money so if you feel the need and have the budget for the RRS ballhead... I say go for it! I wouldn't. I'd put more money into the leg set.

Note: A lot of "traveler" tripods come with a matched head. Some are limited what they can use, if they are designed so that the legs reverse over the head to be as compact as possible.

I have two Manfrotto tripods with ball heads, and one Gitzo series 3 tripod with a gimbal head. They are all great. You can buy another Manfrotto but stay away from the Be Free model. They are crap.

I bought this tripod: https://www.bhphotovideo.com/c/product/1010690-REG/manfrotto_mt190xpro3_190xpro3_pro_aluminum_tripod.html

. . . and this head: https://www.bhphotovideo.com/c/product/1162343-REG/manfrotto_mhxpro_bhq6_xpro_ball_head.html

I bought them last year and got them both for about $233 together. B&H has a great price now on the tripod. But now that Christmas is over you might not see that deal again this year....

But you can't go wrong with a Gitzo. If you are using it for a really big lens with a gimbal head, I suggest the Gitzo.

When it comes to tripods a good advise is get the best you can afford. That has been my philosophy for years but as the time goes by and life makes me wiser my views of a tripod are now different, considering the many choices available.

In 1976 I bought a Manfrotto 2031, a tripod that I still keep. Because of the construction of aluminum tripods at the time this one is already too heavy for my needs. I bought a Gitzo, also an aluminum tripod and I do not believe I have used it more than a few times.
My son gave an Osmond DCF-432 carbon fiber tripod as a present which I use often because it is light although it gets heavy with my Linhoff ballhead on. When I began to use my Olympus bodies I found that these large tripods were indeed overkill for the little cameras so I decided to buy a cheap ($45) aluminum tripod made by Dolica which has been a good buy to the point that it is the tripod I use when I travel, even when I carry a dSLR camera.

The Dolica has been a great buy. I use good tripod techniques with it and it has served me very well. Any of the tripods I have can do a good job and I am sure your Manfrotto can do it too using good techniques. I am not implying that you should not buy what you want. If you feel that any of those tripods will do the job for you just follow your instincts. The RRS BH-40 is a professional ballhead that will do a great job, no matter the subject.

Like most people, i started with inexpensive tripods and soon learned that they were trash. I was excited when i bit the bullet and bought a new Gitzo traveler, only to discover that even the magic name of Gitzo could not overcome the laws of physics. For landscape photography, you need a rock solid base, and lightweight “travel” types with center columns just aren’t steady enough. You’ll have a great opportunity to try them in person, but i would recommend at least a 3-series weight tall enough that you can eliminate or minimize the use of the center column.

Gitzo is a great tripod, lots of well-earned respect among professionals. They have ultralight Traveler tripods - with 4-5 leg sections, and an integrated center column and ball head. They support 22 to 26 lbs, and due to the multiple leg sections, can easily fit into the tiniest carry-on luggage. The Mountaineer group have beefier tubes, with 3-4 sections, and will support from 18 lbs to 46 lbs. Their best tripod - the Systematic - have 3 to 6 leg sections, and can support 55 lbs to 88 lbs.

The way Gitzo rates their tripods is ingenious. They use a numbering system that goes from 0 to 5, with 0 being the lightest duty and least stable. They recommend, based on angle of view/magnification, the longest focal length that can be used with their tripods - using 0 for wide angle, 1 for 100-150mm lenses, 2 for 200-300mm lenses, 3 for 300-400mm lenses, 4 for 400-500mm lenses, and 5 for 500mm and longer lenses. The top tube diameter ranges from a 21.7mm for a Series 0 tripod all the way up to 41.3mm for their most stable Series 5.

Top tube thickness is a very reliable predictor of tripod stability with a given focal length - irrespective of camera+lens+head weight, load capacity (their lightest duty tripod still has a load capacity of 18 lbs), and number of leg sections - a Series 5 with 6 leg sections is just as stable as one with 3 leg sections - contrary to popular myth.

Induro and RRS have similar numbering systems.

I use Feisol tripods, because I am frugal. It has a top tube of 37mm, and with 4 leg sections, can fit in a carry-on bag. It weighs 4 lbs without the head and costs $600. I traded a Gitzo Series 3 for it back in 2006 and saw an immediate improvement in stability. There are others, like LeoFoto, Benro and others that make good products that can serve your purposes without breaking the bank.
