If the prefolp bets aren't too high, I decide on the flop. Then, if it looks good, I usually check to see what the bets are. If they aren't that high, I'll call. If everyone checks, defintely call but be careful, someone could be slow playing a good hand. The turn is usually the most common decider of whether to fold or stay in. You have to rely on your own judgement so choose wisely.
