Do you guys really like the way some of them taste, or mainly do it to get a feel for MO vs 2row, different hops?
They usually taste great. When they don't (or do, for that matter), they provide a great learning experience.
Pick a base malt with the name of a European city in it, a noble or noble-ish hop, and your house lager yeast. Brew it to a reasonable gravity and bitterness with scrupulous technique, and you're going to get a great beer that's a crowd pleaser. I really like Briess Pils, whole German Spalt Select, and Wyeast 2308 right now, but another good one is Munich/Tettnang/2308.
