I like Spike, Oz, Tara, Cordelia and Anya, they are better heroes than those Buffy likes to look at as such.
Still if Buffy steppes out of the Nile and changes her attitude I like Spuffy. The other three almost definitely could do better.
Don't like Angel, am proud to say I was of the few that didn't like him even in the first season. Actually I didn't like him from the moment he said - "I know what your thinking, but don't worry! I don't bite."
I liked Spike from the second he threw the Annoying One in the cage to fry. I needed more time to warm up to Spuffy, but that's because I couldn't see what he saw in Buffy.
