I have the Thule T2 Pro XT and have been thrilled with it. My mom has the Kuat Sherpa and I prefer the Thule. I like that locking mechanism to the hitch is built in vs. having another piece. I also like that each bike has a built-in lock. I use an extra Kryptonite cable to secure the rear wheel to the lock and I feel good about parking at rest areas, burrito joints, etc. and leaving the bikes locked up. I also have a fat bike strap that works really well (I have 4.3" tires and this was the only modification I needed). Roadies with 25 mm tires up to the fatty feel secure and I’ve gone careening down bumpy mountain passes without issue.
