Bitstamp is ok as long as you deal with EUR, not sure how their USD side is. The thing with an exchange like this is that they keep asking you silly questions in order to know more about you.

People are being asked things like how much crypto you plan to trade in the coming months or years, what the source is, if you can point them to addresses your coins are stored in, and the list goes on. It's horrible.

I'm not sure about LBC and their hunger for your information, but at least you're doing peer to peer business, which is better than subjecting yourself to an exchange like Bitstamp or Coinbase.
