I have always been in the camp of hominoid. It just made the most since to me as a child and now. Bipedalism has only been seen in humans and early human ancestors, so anything else would be a bit hard to justify. Sure, chimps, gorillas, and Orangs can walk on 2 legs for a short time (mostly when their hands are full of fruit), but their hips (and leg bones) are not made to support bipedalism for very long. If Sasquatch were some other kind of primate (non-hominoid), we would need some form of evidence of bipedalism in the fossil record (which we don't, to my knowledge).
I don't immediately discount the "woo", but I don't have enough evidence to discount or support it. Classifying Sasquatch as a living hominoid would not be a big stretch of the imagination, as Dr. Meldrum recently posted an article which discussed the possibility of "The Hobbit" still being alive today.
Also, if we compare the reports/sightings with living primates, there is a lot of overlap in behavior- the odds of a supernatural being having the same behavior as a primate are very slim, essentially 0, in my opinion.
