I think it's mostly because I find Kristen to be an extremely BAD actor. Where as David and Sarah both are amazing. Just watching "I Only Have Eyes for You" you can see their excellence.

Completley agree I also think that season 2 finale where his sole is restored and then she kills him is amazing.

D/S are completely one FIRE in every scene!! eward and bella have got noting on them!

Neither. I'm a diehard Angel/Cordelia shipper. They had the most real and natural relationship in the franchise.
I'm convinced Cordy was the love of Angel's life not Buffy and the chemistry between David and Charisma was beautiful.
Neither Angel/Buffy or Edward/Bella have anything on them, in fact, both were immature and unhealthy relationships and in the case of Angel/Buffy illegal!

David and Sarah Michelle had better chemistry than Rob and Kristen even though I liked all four of their characters. I felt real emotion from David in the scenes where Angel was breaking not only Buffy's heart but mine as well. I felt emotion from Rob in the scene where Edward leaves Bella but not as much as I felt from David.
