The BEST available (and you will pay appropriately) is RRS along with Gitzo, IMHO. I am presently using a Gitzo Carbon Fiber model with an RRS Tilt Head and clamp. Twist locks may not be the easiest, but they are the strongest and best. Best of luck.
I got my top end Gitzo and RRS dual tilt head on eBay for about 2/3 of retail in excellent condition. Good deals can be found on eBay if you know what you want, it’s value and have some patience to keep watching...
