I get asked quite often..."So...what's your favorite beer?"
My response is that it depends on several things. My mood, the weather, what I'm doing, how I'm feeling, etc, etc...
As others have said, it's a situational type thing. I like every beer on that list, and prefer some over others, depending on the situation, and those preferences can/will change as the situation changes.
Mowing the lawn = A good Helles or Cream Ale
Warming up next to a fire in the dead of winter = RIS or a vintage Barleywine
and so on...and so on...
The short answer: "It depends"
