As has been mentioned it probably depends on which era you grew up in but it's this one for me. A thing of beauty. It instantly brings to mind memories of League Cup finals, Yorke in his pomp, Brian Little, etc. It forever tied the word 'prepared' to Villa for me.
I don't mind the current badge, it's clean and modern. I'm not one who has problems with the font either. I would have had "Aston Villa" rather than AVFC though.
