A direct front-on view has rarely been flattering to the Hot Toys one. In that particular pic his eyes look too far apart and he looks more aged than Arnie was in T2. Looks its best from other angles and different light.
What I think it has over the EB one is that flat back of the head and the thing that Maulfan was talking about, the distinctive area around his jaw and beginning of neck....can't think of what to call it. I think this unnameable area is what I saw lacking in some of the first few pics we ever saw of the EB sculpt which made him look too boyish, not enough of a powerjaw in profile view.
