re: Coke or Pepsi?

Honestly, neither Pepsi nor Coke taste good straight up, if everyone's perfectly honest with themselves. If you like things sweeter, you'll favor Pepsi. If you prefer things heavier, you'll gravitate towards Coke. Both drinks taste better when they're altered, IMO (i.e., Cherry Coke and Wild Cherry Pepsi are two of the best drinks on the market).

My all-time favorite Pepsi was the Pepsi Twist. Lemon-spiked Pepsi that came out back around 2002-ish but they don't sell it domestically anymore. Got me one last time I was in Japan, however.
