T-Rex is great if you don't mind it looking a little more bulky, but they will protect your fairings. I especially like their left side slider. The only problem I had was with the quick-release rear axle slider. It connects together magnetically and was fine for a while until one day after a ride I noticed it was missing. I replaced it with the standard rear axle slider and now use a standard rear spool stand when I need to lift the rear.
I have used all the above, t-Rex, GB racing, and Sato.
In general I would they they look ugly. But function over esthetics.
I like the Sato sliders cause they have the minimalist look, while the trex are bulky and more for track
