Kyser for convenience and quick change ... Schubb for stability and less pressure on strings (and possibly frets?)
And neck. Taylor guitars may not be affected (I'm not sure) but certainly some guitars owners have found light dents on the back of the neck with prolonged use of the non-adjustable Kyser types
I have both and it's just as you say spring loaded for fast use. I once saw Tommy E. pull off a capo in blur of one beat between 4 and 1 in the count. He deliberately stood next to a stand where his left hand could drop the capo and then immediately be playing in the new key. His hand only moved about 12 inches. I was impressed.
For adjustable I like the little Planet Waves NS capo. Works on everything. One hand with practice (maybe). Does not pull strings out of tune when adjusted properly. I bought one in black so it wouldn't stand out and look very pro, but I can't find the darn thing half the time so the next one will be silver.
