++Shagrat
He always struck me as.. well... more sneaky and less of the Schwarzenegger-type.
Although, Gorbag might even be smarter after all, but Shagrat has the "home ground" so he does look like the smart expert. I don't know, it's maybe the same as that I always liked Grishnákh more than Uglúk, although Uglúk is the one more "worthy" of liking of those two.
