just ge the cheaper one that has a good track record for reliability.
believe me, i still rock an old intel ssd sata2, even back in it's day it wasn't the fastest, far from it actually. but back then, intel was probably the most reliable, back then the fastest ones tend to fail a lot, good thing nowadays ssd's are more reliable.
my old intel still has my os, still boots in a few seconds (i think 13-15 sec). even if my new one shaves 5 sec from it, it won't matter much.
