Miller.
Why? Because I can make anything else myself. But I can't make a 4% light lager that's in cans for any tailgate and on tap at every sporting event. I like craft beer as much as anyone, but I've reached the point where I can't have more than one 5%+ beer without getting really tired and I usually won't sleep very well.
If I'm having a beer to pair with a meal, of course I want good beer. But I've got plenty of that in my basement and, without that, have tons of wine as well. But at a social event ... I want Miller Lite. Honestly, I enjoy it now more than I did before I started home brewing.
I took a friend to an NBA game last year and got floor seats. He bought the beer and we had Smithwicks and Prohibition Lager, and I really kind of missed having a Lite. It just tastes like sports to me.
