Cordelia all the way. As I said in the other post, I didn't mind Buffy/Angel, but I never saw it working, whereas I actually wish Joss had given Cordy and Angel at least one day of couple's bliss.

I can also see Faith, just because I felt like two times when she needed someone, he was the one who came through, or tried at least. The only thing is that it would be weird if he dated yet another slayer, especially one his ex was friends with. (Then again, Buffy and Cordy were kind of friends, but... nothing like Buffy and Faith were. I think they mostly just tolerated each other for Xander's sake and because they were saving the world together.)
