Why don't you decide for yourself?
Download the free 30-day trial of Elements 15 from the Adobe website and give it a try. You might want to purchase one of the guide books for it in advance (Amazon lists several... Scott Kelby's are good), to be able to use it to best possible extent during the 30-day trial... then decide if you want to pay the license fee to keep it... about $80 last time I looked. Nice thing about Elements is that it has built in support for new users. You can choose between using it in Beginner, Intermediate or Export mode... and can switch back and forth between them at any time. Elements is designed to be an all-in-one software.
The same free 30-day trial is offered for Lightroom 6, Lightroom CC and Photoshop CC. But those don't have much built in support and are more advanced DAM tools, so be sure to get a book in advance for LR6/CC. Anyone other than highly experienced users of recent versions should forget about doing a trial with Photoshop. It's way to advanced to learn to use in a 30-day trial.
LR6 is a perpetual license version costing around $145.... LR CC is the "cloud" version offered by subscription ($10 a month when you prepay a year... including Photoshop CC, which is MUCH MUCH more complex and advanced image editing, manipulation and optimization software). LR6 and LR CC are basically the same, but LR6 gets new feature updates at a much slower pace (probably deliberately because Adobe would rather you subscribe to LR CC).
Photoshop is now only offered as CC and by subscription (with LR CC... the two complement each other... each is sort of incomplete without the other).
There are plenty of other programs that can help.... free, low cost, more expensive.... simple, moderate and complex. Depends upon what you need and want to do... but I got tired of the problems with freebies (no support or updates, discontinuations, etc.) Spend a little on something tried and true... rather than having to start over with something else in the future.
If using a PC with Windows, a codec such as FastPictureViewer (
https://www.fastpictureviewer.com/codecs/) that costs all of $10 can be helpful, allowing you to see most types of images directly in Windows Explorer. I use it for for simple organizational purposes, which is about all it's good for. There's a bit more expensive ($50) FastPictureViewer Pro that has some image editing capabilities, too.
You might want to get and read "The DAM Book - Digital Asset Management for Photographers" by Peter Krogh. I found an early edition of it very useful some years ago, when first getting into digital imaging and before I'd accumulated too many files. The sooner you get organized, the better... since image archives seem to grow exponentially. I now have a couple million images so it would be a massive job to make any major changes to my organization. I'm glad I took the time to read a book or two and "do it right" close to the beginning. At least in the edition I read, Krogh recommended some specific software and devices which I didn't end up using. Maybe his latest edition is more broad or discussed more options... But I didn't have any trouble choosing equivalents to what he recommended.
