I'll be honest, I think all the changes and redesigns worked best for everyone. All characters look more memorable or at least more unique. The only thing I think I preferred before was the main villain's chest decorations (that thing just looks like it would hang loosely, it doesn't seem comfortable) Oh, and too bad that LOP song won't be able to used again, at least lyrics.
I really dig the concept of the armor. It's really creative way to put parts swapping to good use.
I think my favorite is Pantera. Usually, those toylines barely have any girls, and when they do it's a standard human warrior girl or magic girl. But here, a complete monster. Not even a cute catgirl like Kitrinna or Netflix Catra, just a beast.
