I voted Angel, maybe because its more recent or something; though i always preferred buffy as a whole because it was the first ever series i got completely hooked on, i think Angel has more meaning...the ending did seem very forced with very little build up but i liked the way that each character had a purpose, i thought it was better than jsut having a final big battle as they did in Buffy and in many films and i think the deaths were very effective though i have to say Fred's death was the most dramatic (probably because they dedicated a whole episode to her so you had time to think about it all the way through)
Though the Buffy one had the entire season to build it up, I expected there to be more casualties (I think it makes for more drama) but they hardly dedicated any time to the death of Anya, and though I was satisfied with the ending, I don't think it did justice to the series; if the season 5 finale of Buffy was its end, it would have been better than Angel's; I think that Buffy making the choice to sacrifice her life to save Dawn's would have been the ultimate finale.
