Not really sure I want to jump in on this debate, but Cursive and The Good Life are two of the most consistent live bands around these days - especially Cursive. I've seen both bands many many times, and have yet to be disappointed. Bright Eyes, on the other hand, couldn't be more inconsistent in performing. No matter how much I love them, I have often walked away disappointed. I'm not even sure who you guys are criticizing anymore, but if it's Cursive, I would be very surprised.
As far as BDB vs. BSP... last time I saw BDB he was horribly rude to the crowd. I seem to hear this all the time in reviews. That's not my cup of tea, so I think I'll be catching BSP.
