i drop the saddle all the time (for the downhill steep twisty bits) you can move your body around more and corner better with lower CofG.
this suits the kind of riding i do where you climb up, lower saddle and do a nice bit of singletrack down.
gripping the saddle with your thighs is no good if your backside needs to off to one side when cornering or riding off camber.
i guess whatever works for you.
not bovvered with a gravity dropper though just a decent qr.
