My favorite is Gale, I usually play Wizards, and really enjoy talking about magic with him, and like the attitude they gave him. His background story could be toned down bit though (which is true for all of them - none of them seems to be a believable level 1 character, but I'm not that bothered by it).
My least favorite is Lae'zel. If there was a good alternative I'd never take her along.
