Trust me, I've played PLENTY of Guilty Gear, but upper level matches aren't THAT offensive. Most characters have some odd corner trap and otherwise a couple of setups. In fact, that video you just showed kind of proves my point. They just keep going for the same setups. BlazBlue is somewhat the same there, but it looks like everyone has many many many more options.
Honestly, I've played too much Guilty Gear. It's somewhat like KoF in that, I've played each version as it's come out and aside from damage changes, characters get maybe one new move or one slightly changed motion. It isn't enough to keep my interest anymore. Accent Core might be good, but I really just don't care about those characters at this point.
From what people tell me on BlazBlue, pretty much everyone is good at higher levels. The smaller cast allows for much better balance. Tager's the only one that I haven't seen too many videos of but even then, the few I have seen have him matching up just fine.
I don't see the designs as generic at all though. I just see an artist sticking to his style, which works really well because they're all awesome.
