I don't know if my post was misunderstood or what, but I'll try to clarify. Japanese smash is a disadvantage for King Funk because he's used to NTSC. Whether J Falcon is better than U is irrelevant. Also almost no DI is a disadvantage, since he's more used to try to DI and more used to combo against DI (therefore less skilled to combo against no DI than people who've been comboing against no DI forever). Single elim is a disadvantage for King Funk, because although most European aren't that good at comboing / 0 to death, they rely on "smart" play, ie reading/punishing habits and stuff. So it's kind of hard to adapt in one single 4 stocks match.
Now don't get me wrong, I'm not trying to pre-john for King Funk, I do think the disadvantage isn't that big and even if there weren't any, I don't think he'd beat everyone. Even that is irrelevant, I'm sure his goal will be to have fun and to discover some cool/different stuff.
I for example, the few times I got to play with Japanese players (online), learned some things.
