Might as well chime in..
When out at the pool hall for hours, I'll do two pitchers of Coors Light. I'll put two salt packets in the first pint out of the pitcher, and add a salt packet every time I refill.
When hanging out with friends, I'll either drink whatever is available, or get a 'make your own six pack' from the grocery store, which usually contains 6 different ones, and I try to get ones I've never had before.
When at a good bar, with a wide selection, I usually go for darker German flavors. I used to get one from my favorite place that was called a 'hacker' (The real name was hachersomethingorother).
Picking a favorite comes down to situation. Hanging out for hours with friends, I go for something light on the pallet. With good red-meat food, I prefer darker and full bodied. For casual drinking when I don't feel like participating in mixed drinks (usually when I'm designated driver), I'll go for a few 'fruity' types (they are like beer, but with either fruit in the brew, or juice or something). Regarding drinking as designated driver, my limit as designated is 1 bottle or pint per hour.
Whenever drinking a not-fruity brew, I usually add a dash of salt to each serving, unless I'm consuming with something salty being eaten.
