I wouldn't call the character designs anything special. A lot of them felt very samey and uncreative, with far too many characters having similar face structures and helmet designs. A lot of them lacked detail, too, and felt very flat and underdesigned. (RID is even worse in that regard) They feel very safe an inoffensive, like the designers were afraid to take any risks with visually diversifying the cast too much. And while I think the vocie actors chosen were spectacualr choices, so many performances fell flat due to the unnatural dialogue and terrible direction.
