Which of these is best for 400MHz@Cas 2?

All right, I've seen plenty of threads on the different types of memory, let's see if we can't get some consensus on this.

Looking for some memory to do 200 MHz at CAS2 (preferably the most aggressive timings). From reading the various threads, I've got the following possibilities (in no particular order):

Crucial: PC2700
Corsair: XMS2700
Corsair: XMS3000
Corsair: XMS3200
Mushkin: PC3000
Mushkin: PC3200
Samsung: PC2700
Samsung: PC3000
Samsung: PC3200
Kingmax: PC3200

Of those, which do you feel is the most likely to hit my goals.

The only real Samsung out right now is the 2700 version. That one seems to be most consistantly the best and is the one that Corsair and Mushkin use on their highest end products, but you can get the same performance if you get a Samsung branded module and not just a generic PCB that uses the same chips.

The best DDR in the market known....is the Corsair XMS PC-3000
185 Mhz Cas2 @most aggressive settings.

corsair 3000 and 3200 are pretty much the same. 3200 is rated
at cas 2.5 and 3000 is rated at cas 2 which will do vice versa (spell)

i think your best bet would be with the corsair or samsung. not
the crucial.
