I see the Hound as a very versatile fighter as well. He's like the Jackie Chan of the show. He is very well trained, knows a sword, and uses everything to his advantage. His greatest strength I think is his ability to see an opportunity. He will mess around with a sword with the best of them, but as soon as he notices a chance to break someones jaw with a punch, or a headbutt, he takes it.
Bronn I feel is very similar to the Hound, except he learned fighting in a different environment, among theives and trickery, so he is far more knowledgeable in opportunity sight. Where the Hound is a guy who sees an opening in a parry, or a block, Bronn is the kind of guy who creates the opening. several moves in advance. Oberyn is like this too.
The other thing I'd like to note is that Jon Snow is like half the age of all the others.
