Both are a hassle, but the emo-performance guy is the lesser evil.
Honestly, the guy who talks down to you is by far the tougher one to deal with. The emo-performance guy is still just desperately crafting a 'self that wants to be seen,' so if you become close there’s a chance you’ll see his true self. But a guy who acts like 'I know more than you, you know' isn’t interested in this world or these emotions, so a conversation can’t even start.
