The Cheetah, being gated, is easiest - basically one motion to change gears, and intuitive; I don't have to look at it when using them.
I've even had a buddy with a ratchet in his car get the hang of the Cheetah immediately, and he liked it.
Ideally, you could compare them all yourself, as you'll get different opinions, but I've used them on track and on the street with no issues.
