@historyofpunkrock I'd go with Fresh Fruit for Rotting Vegetables, though It's Alive is a good choice. I'd like to have seen London Calling on the list, which I much prefer to Combat Rock.

Edit: D'oh. You're asking about the best of all time, not the best of those shown. But I'll stick with Fresh Fruit. Appeal to Reason has gotten a lot of ear time lately, though.
