Original is my favorite overall. With the mask I might even rank Wolf over Pussyface, I feel like Wolf design is a little of a mix between the designs from the first 2 movies, preffer his mask and armor design.
But then with mask off, Original and Pussyface are equal to me. Like most of the Lost Tribe pretty much, they are all awesome.
After them the Berserkers from Predators I guess, then Fugitive, then AVP preds, the Upgrade at the bottom.
