DMC5 is the best DMC and one of the best action games ever made but NG Black/Sigma is at least as good, and beats it in out in ways like level design by a mile. They're both Top 5 though.
Even later NGs don't have good level design compared to Black/Sigma though, so I don't know if a 4 would. MUA3 while good is also mostly hallways. Does Nioh have good level design?
