More Lovable Longshot? Gilles Muller or Mardy Fish?

Question

Which longshot odds on loser do you want to win the tournament more? Mardy Fish, the upstart American veteran, unseeded facing the new world #1 Nadal?

Or

Gilles Muller, the only qualifier to make it to the 4th round and now the quarters, against the #2 seed, but 4 time defending champion, Federer?

It is highly unlikely either will win against the favorites, but if either were to win, you'd think they'd have a good shot at the Final and maybe a win.

Answer 1

Mardy and Fish are more fun than Gilles and Muller.

And who could resist yelling "GOOOOOO FISH!!"  

Answer 2

Mardy Fish USA

Answer 3

Mardy Fish is certainly more "lovable". He's been around a long time; his best buddies have done better than he has and he might finally have come into his own after injuries and lack of mental toughness. He is also reputed to be a "nice guy" by others in the locker room.
