I spent ages trying to complete DMD mode with Vergil and Dante to get the super costumes. But now that I have them, I don't use them because it just feels too easy. I prefer to play with his standard costume to work on the S and SS rankings. There's not much point using those extra powerful costumes, there is no satisfaction. But at least with Nelo Angelo you get to do different moves so that's sometimes fun just to play around with.
