(9)Sandor Clegane - Dany is cool and all, but alternates between Mary Sue and inept leader (and no, the two don't even out). The Hound, on the other hand, is a really good character, that fits perfectly within ASOIAF's universe!
(5)Tywin Lannister - Victarion's a bit bland. Tywin is an extremely underrated villain, ruthless, smart, with a bit of hypocrisy to boot and a believable backstory. No question here.
(3)Eddard Stark - Now this one's a bit harder, as I find both characters to be equally good. Thus, I'm going to play favourites and vote for my man Ned.
(10)Jorah Mormont - Bran is lame (no pun intended). Jorah's alright. Weakest duo of today's round, IMO.
Edit: I expect Theon to crush Syrio next round. I also think Jon/Varys will be very close, but contrary to my earlier prediction, I think Jon wins. Still think Theon will win that division, though.
This round should end with Hound > Tywin, Ned > Jorah and Ned > Hound (although I'd rather see the Hound beat Ned), but the final match is a toss-up.
