I voted for Alpocalypse. SOL had funnier parodies than originals (which is odd for me to see an album of weaker originals) and White & Nerdy is much better than Perform This Way. My second favorite song on SOL is Don't Download This Song. As TMBJon said, the highs are higher on Alpocalypse, but Alpocalypse is consistently strong.
My favorites on Alpocalypse are Party in the CIA, Skipper Dan, If That Isn't Love, and Polka Face (A little different than my initial 2 listens.)
Alpocalypse isn't as good as Running With Scissors (my favorite), but is tied with Bad Hair Day for me.
