I like both, Bangel for all the 'angst' and intense love, and it was just stuff legends are made of.
However, I did like Spuffy as well, for the fact that Spike understood Buffy more than she did herself at times , or wanted to admit to anyway - I always thought Spike would of been a good psychologist 'lol' He really did get into peoples heads & he knew what made them tick! Oh, and yeah, plus I liked that Spuffy was more physical than emotional too ....sex is good, even if it's just sex! 😀
