I actually just got done installing one (PSA EPT). I like it, for the price. I normally just use mil spec triggers (though I wind up throwing a lot of the out if they're bad), so I don't have much to compare to. I've only used mil spec, ALG QMS, POF 4.5 curved (my favorite) and now PSA EPT. One thing I dislike about this trigger (same complaint about the QMS) is that the reset is so far forward, and the amount of release pressure is so little, that you practically have to take your finger off the trigger for it to reset. It also seems like a delayed reset, as if it almost doesn't but does at the last nano second. Mil spec triggers, IMHO, have a better reset. I would opt for the EPT over the QMS since my QMS has HORRIBLE reset feel (it's a super clean break, but the reset feels like the trigger drags on gravel before it finally resets). My EPT is smooth both ways. However, one thing I like about the QMS better than the EPT is the (minimally) oversized pins (and you definitely can tell the difference when installing. ALG pins fit much nicer).
So I'm kind of "meh" about both the EPT and QMS. I think I'd stick with mil spec (although the better ones) and skip the EPT or QMS (unless your serious about triggers, in which case you'll get a cassette type anyway).
Just my .02
