I'm glad to see that Wario got his classic outfit back. I preferred that outfit over the WarioWare outfit. I'm used to the classic outfit rather than WarioWare for a few reasons. For the first, I never picked up any of the WarioWare games, for they didn't seem appealing to me in the least. Secondly, I preferred the side-scrolling games of Wario Land, and the Gamecube game Wario World, which he donned his classic outfit.
Though, I must admit, I cannot see Wario driving that motorcycle while in his classic outfit. Seems more of like what the minigame-Wario would drive. We all should know classic Wario drives his purple 'Wariomobile', which looks similar to that of an older Cadillac. I could have seen him drive that instead of a motorbike, seeing as Wario is more wealthy after the first one or two Wario Land games, as well as after Wario World.
So, honestly, both costumes are about even on my terms. There's my love for the classic plumber look for Wario, for it was what I grew up with. But then there's the fatc that Wario-Man and the motorbike are more of what WarioWare's version of our famous treasure hunter.
