as far as photographic evidence goes, yetibombz wins the physique contest - wiggs has superior mandibular development but yeti takes the rest.... wiggs just looks like a couch potato so it's not much of a contest, admittedly.
as far as intellect goes - wiggs believes in giants, the illuminati and the impending end of the world. I think he is a very broad-minded chap. yeti understands the theory of relativity, all kinds of philosophical conundrums and has had many paranormal experiences. this one is a toss-up.
