My favorite is Guiness. In the summer, I like some of the fruity beers such as Dos Equis, Blue Moon, or Lienies Summer Shandy. Warsteiner, Asahi, and Red Stripe are a few other good ones. For local breweries, Schell's and Brau Beer both make some pretty decent stuff. I think the only one either makes that has any national recognition is Schell's GrainBelt Premium, but I'm not sure on that. When I visited AZ a few years back there was a really good local brewery I tried called Oak Creek or something like that.
