OH MY GOD, HOW COULD I FORGET IGNACIO SUAREZ??? *facepalm* He would've made me really torn about choosing Keith Mars as my favorite.

Yeaaaah...pretty sure John Winchester, Uther Pendragon, and Walter Bishop could give him a run for his money there. You will note that I made sure to ask for "favorite" rather than "best" -- that way would only have led to madness. :)
