I think it will be interesting to see how these changes affect the 501st type accuracy seekers. Everyone wanted the wonkiness since it was on the originals, but really all logic dictates that they should look something more like what we have for Rogue One. I'm still loving the the wonky old stuff, because it "feels" like Star Wars and the artist in me longs for the hand made-ness of the old films. But perhaps many of the accuracy buffs are in it more for the baseball card collector completeness than the artistic part, and maybe the new troopers will settle in as the "best" representation. It certainly does dilute the pool of what "accurate" means!
Personally, I find the perfect manufactured look a bit boring, just like CGI models. I'm happy to watch them on film, the new Falcon looked amazing in TFA, but I have no interest in looking at it outside of the context of the movie.
