The suit designs are still very bad to me by a big margin outside of two. The belts aren't that great either and that final form is really bad. Yet the series itself was so good I overlook the designs and enjoyed a lot more out of it. Some shows can have amazing design (Wizard) yet fall flat too.
I think that might be me to an extent. The suit designs took me awhile to get used to aside from KR Para-DX and like you, I think it had a bit more due the story than anything else. I didn't get the final form either. I'd take Beast's final form if they were to do that frilly stuff any day.
