I didn't do the poll thing. But it's a tie for me between Five By Five-Sanctuary and Salvage-Release-Orpheus. As for how I see the relation between shows, in Buffy 1, as I'll call it, she begins her descent into self-destruction. In Angel 1, she begins her redemption. In Angel 2 she proves that she's back and fit to command. In Buffy 2, Buffy treats her like garbage, thereby proving Angel right, when Angel had told Faith prior, you've got to change, and it's gonna be hard, because there's gonna be people like Buffy who dont' want and/or aren't ready for you to change. But Faith took it like the studette that she is. As I related elsewhere here, pity that the show ended with me having all the love in the world for Faith and much less love for Buffy.
