Like? I can't really think of anything, except stuff that Japanese players leave out of their metagame because it's inferior.
Also that thing about Japanese players disregarding meter management/building is nonsense...if anything, they are more aware of how much meter they need in a particular situation than other players are. But sometimes you just have to take out a character when you get the chance...does Bala know nothing about meter management because he had to use 4 bars and HD against Madkof's Chin when it didn't kill him and it wasn't Madkof's last character?
Going by my own experience, and most of what I've seen, lots of Japanese players will go for whatever will get a HD combo off. That plus the rarity of ever seeing a team that didn't have a Karate, Beni, Shen, or other characters who use them as their strongest link, unless you're prepared to make them their weakest link. There are some great Japanese players who mix things up in characters and tactics, just not as often as I'd like.
By Korean, I'll just say CafeID, but the difference with them over many Japanese is they'll go for the available hit, and don't rely on HD combos or cancelling. My latest fight against Verna was his Terry with a fucking crazy yomi, and at least one fight against him (and MadKOF once) involved a excellent-timed raw HD. Maybe Japanese players like Shokti or Haregoro do that, but they don't do it as consistently.
I won't argue over who's better, though I have an opinion on who's better now, but I expect that to change as time goes on. It's good enough that there are a lot of great players, and multiple playstyles out there to make things even more interesting for learning and competing.
