Looks like a list of the most commonly found canned beers that arent labelled Budweiser, Coors, or Miller.
21st Amendment beers are pretty good and they're all in a can. Modelo isnt bad for a mexican beer and it's available in a can. A lot of Avery Brewing company beers are available in a can, the Ellie's Brown Ale is especially tasty.
Gennessee tastes better than PBR but the hangover just isnt worth it.
