Isn't the benefit of a stop and go that, if Villain has overcards and doesn't hit the flop he'll likely fold and thus not get to see the remaining cards that could beat you? Whereas with a push he might likely call and get to see all 5 cards, as opposed to only 3. I think that play has some merit in this situation for that reason, though I don't know if it's superior to a push.
