I can vote for the Crucial m4, bought it a few days ago and it's indeed very snappy. I chose it just because of the reported problems with SF-2200 series drives. I just wanted to be on the safe side and the m4's are no slouches either. The perf/$ is great and the new Samsung 830 can't beat these there.
Boot times are great and overall windows feels faster. Haven't experimented too much with game load times but they are a bit faster too.
I have it installed on the Marvell on-board controller using msahci driver for trim so it's not the fastest in benchmarks. With those Z68 boards and Intel 6G controllers they are even faster.
