i agree, it's the wrong kind of question (though still a good one).
everyone's taste in their equipment is very personal, and not one amp or speaker is better than another based on what you prefer to listen to and how you listen to music.
your other components and room environment will play a huge role in how you enjoy the music.
all the amps mentioned are among the better performers, but how can one really say one is better than the other? in certain categories perhaps, but not across the board.
