Loki messes with beings on his own level and still tricks them. Of course, the people he deals with seem extradinarily stupid when dealing with him especially considering that they already know how treacherous he is. Q has smarter opponents but usually there's not all that much of a trick to it. A hidden agenda yes but not all that crafty.
