I can't say that I think 21st CB is better than AI, but I definitely love it. You are young, so you would not have been around, but AI came around just when the country needed something to fight for. It was timely and totally relevant. I feel that Billie's vocals on AI captured the sentiment of every song so perfectly, but technically, his vocals were his best ever (except for Foreverly) on 21 CB. RHS is one of my favorites and EJN just captured the anit-religion sentiment so perfectly.
