If you play enough you end up ranked pretty well with each character from what I've seen. So with that in mind I'd just play who you want and after a few games you should be playing pretty even competition. I have more games played with DK than anyone else but he's nowhere near my highest rank. But I still have a positive win rate with him because of who it matches me with.I'm quite bad. I remember the days of Melee when I was pretty decent with Falco.
I guess Ike is my main in this version? Even though I don't like him that much.
