Never really thought about this....but think I would have to say Buffy. I mean I'm generally the leader of the group...and in the show I tend to agree with Buffy almost all the time so maybe that means in the same situation I'd make the same decisions? And in college (which is like the last two years of American high school for those not familiar with the UK school system) I was definitely a Buffy....so yeah, Buffy. Perhaps with the teeniest bit of Faith at times I think....
