Heh, someone took my advice, didn't they. (^w^)
Anyhow, considering how well Meiling held up against Yuugi in "Burning Meiling", I'd definitely have to go with her. I mean, at the end of the day, she is a youkai and therefore much stronger and tougher than a regular human, no matter how buff they are. She also has the benefit of danmaku, unless you're making it a rule that she can't use those of course, but even then, she's a master of Kung Fu and easily the most skilled fighter in Gensokyo. (^_^)
