I agree with them getting a bit carried away with the details on the BvS suit. All the line patterns on the MoS suit seemed to just have a better flow than what they did on the BvS suit. Plus, it deviated from consistency to me on what was established as the Kryptonian suits to be (both Zod, Faora and Jor-El all had the same suit design as Superman), so I didn’t particularly care for that aspect either. I get the whole “selling toys” thing so different looks are desirable for each film, but still.
And I don’t know about the BvS figure being an overall better figure than the MoS one, at least for me. Going based on the stock figures sans any mods, the suit texture, trapezoid area and cape were an improvement on the BvS version, but I think the the body, sculpt, and suit design of the MoS figure is better.
I have both, and I’m fine with those as my Cavill Supes. I have both a MoS and a BvS display. And then a WW 2017 display as far as the overall DCEU goes. Not interested in anything else beyond those.
