I think Cat Deely's question was a little lame. There is simply no comparison between BJ and Sum 41 because they are different genres, like someone already said. Sum 41 are a punk band who play hard and fast. That can be alright, but I just remember seeing them on TV and thinking "What the....?". It's all about opinion at the end of the day. I just don't like punk really, and that's just me.
