The SSAs are fine. I've found them to vary a bit, but all are, of course, very usable and very reliable. I've also found them to stay relatively consistent as they get dirty. I just, personally, have liked the MBTs press and reset better, but some don't like them at all. This is purely a gamer answer, but once I've gotten used to shooting a MBT (after maybe 20-30 rounds), I find it much harder to short-stroke a MBT than a SSA. Admittedly, that may be partly due to hopping between the two, but I'll tend to stick with a specific trigger type (SSA or MBT) for several range sessions at a time.
Bottom line, if you put a SSA (or G2S) in a gun, it will work and suit your needs fine. I wouldn't have any doubts.
