Which of the two Thief dagger classes now feels better to play?

AFAIC, playstyle always trumps sheer damage (as long as damage isn't so low that the player gets a bad case of green-eyed inferiority complex). If I get bored, I'm hardly going to be able to appreciate the damage, after all

My main character is a Buccaneer, so I know how shoddy it is to play a class all about unique play style but damage being so sad the only class we were beating in damage on a consistent basis were mages.
