Each of them uses synchronous NAND Flash, so they would all be the same.
cept for Max IOPS which uses toggle chips which is just a tad faster
BUT, know this, that the new firmwares were released fixing MANY BSOD problems, including mine.
(sandforce found a problem so they sent a fix to all companies to incorporate it in their own firmwares)
I own a Force 3, and an Agility 3.
I took in consideration that in the corsair forums, there are threads for the Force GT series for problems not in the Force 3 SSD's
And also in the OCZ forums, its the same thing with The vertex 3's, and not so much problems on the Agility/Solid series
All in all, the new firmware (2.15 for OCZ & 1.3.3 for Corsair) SHOULD even out the
reliability question here.
ALSO Corsair IS the BEST for RMA's just in case anything happens
EDITED: Galcobar corrected my mix up between synchronous and asynchronous
