I like root beer no matter what brand it is. I like the A&W out of the jug when you buy it from the A&W restaurant. My top 3 are IBC, Stewarts and Barq's, and Barq's does have bite.
They had some commercials of that not long ago. I think Rawburt just don't watch much TV.
Edit: This thread made me have to go down and get me one of my IBCs from the fridge, I also have a 32oz Stewarts too I need to drink sometime.
