I'm still no good at Royal Guard. I need to practice with that style more. Watching the videos of enemies getting clobbered in one hit with Royal Guard is quite motivating, though. --- Newer isn't always better. And I shall keep Dante's Force Edge polished and sharp till he comes back.
I had to go with Gunslinger. I was tempted to roll Royal Guard but with how soundly DMC4 thrashed it relegating most of its usefulness to straight Royal Releases (Which look fantastic, mind you), Gunslinger is still quite fun and it's the only time my guns will see any use in these games.
/which makes it missing in DmC hurt that game so much more - A single A+X input is not an adequate replacement.
