I gotta go with Keystone Light. IMO it has more beer flavor, but you can’t beat the calorie/carb count of natty. Both beers are refreshing. Busch light is a little better than natty IMO. Cheers!
Before I watch I'm guessing you're going to guess the correct beer and your favorite is going to be Natty SPOILER ALERT Edit: I was right! I personally think I would choose Keystone, the one time I tried Natty there was something in the Natty I just did not care for, sort of metallic. I should l try it again just to see
