He is like a suped up MP. I would say BR is only better technically, while MP has an incredibly unique and influential style. esp. circa FII and SFAM.
BTBAM can be explained by a certain energy throughout the songs. You can tell they love the writing process and the music represents that. Whether it be a softer part, noisy part, or melodic section, the energy continues throughout. It took me awhile for BTBAM to not seem contrived to me.
BTW: LISTEN TO THEM! DON'T PUT THEM OFF FOR HOW THEY LOOK!
