I always go for Row 1 if at all possible. It's hit or miss on the bulkhead legroom; at 6'1", I'm sometimes a little cramped and sometimes have so much room that I can stretch out or even cross my legs if there's no one next to me. Better, though, you don't have to put a bag under the seat in front of you and kick it the whole flight, and you're the very first one off the plane (I know you're flying domestic where this isn't as big a conceern, but it's a huge bonus if you're flying international and don't want to wait behind the entire rest of the plane in the immigration line).
