The KT333 has been out for some time now, but true PC2700 DDR ram has been slower to come by. There are boatloads of overclocked "PC2700" modules out there, but Crucial is one of the few whose ram is certified for these speeds...
Crucial's ram, in theory, should run more reliably, and produce fewer memory related errors since it's built on a 6 layer PCB process, and is officially JEDEC approved. They're also not a fly by night operation, and have tech support that will actually provide tech support. Remember that, as a lot of "PC2700+" ram probably doesn't fall within specifications.
