I'm going to have to go with the Mayor because (a) he's a Big Bad and (b) he's the best of those, with his common sense simple virtues neither being an act nor touching his pure evil and his and Faith's completely twisted relationship. "There's nothing uncool about healthy teeth and bones." "Miniature golf!" Spike and Dru are fantastic but got displaced in the season by Angelus and, while Angelus is probably Buffy's personally toughest Big Bad, he's sort of something else - the Crossover Bad. And Spike's almost the reverse and a lot of Spike comes from the less-Bad phase. Unfortunately, while Dru was wisely kept as a recurring character we never got enough of her. And Faith would give Angel a run as a Crossover Bad. The s2 Bad cluster of Angelus, Spike, and Dru vs. the s3 cluster of The Mayor and Faith would be tougher to decide but if I have to pick one entity out of all of them as a pure Bad, then, yep, The Mayor.

And then Ethan Rayne is just a blast but is decidedly minor. I bet there are several minor bads who I might include but I'm not thinking of. For instance, Mr. Trick isn't my favorite but should be on the list. Of the rest on the list, not so much, though Glory wasn't a bad Bad. She was the last decent Bad - the worst are easily those from s6 and s7.
