So looking at all these pics other freaks have posted of the Hot Toys ESB Vader, I could not help but feel it looked familiar:
The pic on the left is courtesy of Kylo Ren,the pic on the right is my Sideshow ROTJ Vader head modified with the much larger Hot Toys Rogue One dome. To me this combination looks eerily similar to the newer Hot toys ESB Vader head sculpt.
I remember alot of people complained the Sideshow mouth was too large, perhaps not after all? Originally the Sideshow's smaller dome may have exaggerated the effect, because it looks fine to me, and more proportional with the Hot toys rogue One dome.

I'm still undecided on the HT ESB helmet but not sure I agree. The SSC has those dead-flat cheek tops, the mouth triangle extends too far down so seems too big overall and too wide at the bottom. He has that 1970's comic Vader look. Those were the two things that killed that SSC DX effort. There's other flaws too - the lower "eyelids" are noticeably too big/high on the SSC, and a somewhat undersized nose. Overall, the lower face seems too big in relation to the eyes on the SSC DX.
While the two at a glance seem similar, there's also some lens distortion in that pic of the HT ESB, making the mouth triangle seem more prominent proportionate to the overall face (the very thing that stands out as the most noticeable flaw in the SSC DX) in that pic than it does in others.
