I have to say I'm pro vista as I am currently running Vista ultimate x64 and have virtually no problems (only with formatting drives manually).
I dislike when people say "more resources" since every next gen OS should since its meant to be a step forward so obviousley it will require more power, I believe it has many more benefits then xp and previous os as long as you get used to the incremental changes within the architecture of it.

However these days its up to the user so if you like it, you like it, if you dont, you dont.
