Ive ridden both, had rossi pivots first then deadbolts then fks then sth finally back to fks. FKS are by far my favorite. Didn't like the switch from pivots to deadbolts. The release seems similar to salomons, which feel less elastic when they release. Just pop your out. Because of how quickly they release it felt almost random sometimes. The FKS have an even better release feel than pivots, deadbolts or sth. Its a good blend of sturdy feel, while still releasing when needed.
Also, my fks are just about indestructible. The only problem (beside bent brakes) I've had was related to a pull out. The heel peice pulled 2 of 4 screws out. I unknowingly continued skiing, but noticed weird release. It turned out that because the heel peice pulled part way out, I managed to bend the baseplate. Rossi came through to the rescue. This damage happened within weeks of getting them from a guy on tgr (this was the second pair I owned). Luckily rossi warrantied it free of charge.
I also have jester's now. Got them used with a pair of bentchetlers. They have a similar feel to the rossi's, however a little bit closer to the quick, less anticipatable release I found with deadbolts and salomons.
In short, I recommend the FKS as the best binding (out of quite a few) that I've ridden. The jesters provide similar release feel as the FKS and may help to avoid headaches with broken brakes. However, the FKS are by far more durable (than any binding I've used).
