High Life is pretty good. MGD isn't bad, but it's not good either.
By pure volume, PBR is my #1. However, in the same price bracket (the ~$7 1/2-rack of cans), I slightly prefer Olympia.
Bud, Bud light, Busch, and all those other football beers, along with all animal beers are disgusting to me. Budweiser especially is just nasty. And Coors light. Yuck.
Into the next bracket (the ~$9 12-pack of bottles), Henry Weinhard's is pretty decent, and their Summer Wheat is a really good approximation of Blue Moon, which is one of my favorites but costs a bit more. I also like Molson Canadian here. Well, I wouldn't say I like it, but it's acceptable. Kokanee has worn out its welcome with me after being a staple for a long bad period of college.
Above here, we're not talking cheap beer anymore.
