For at home comsumption, my two favorites are 1.) Guinness Draught (the can, not the bottle) in a mug with a jigger of Smirnoff added (two of those will calm you down) or 2.) Carlsberg Elephant.
If I’m at a pub, I’ll order Fuller’s ESB.
At a social deal like a crawfish boil or some such that’s liable to last a long time I stick with Miller Lite or some such that won’t shorten my legs too quickly.
