volume 1 and volume 2 are completely different movies, so the edge of the music is gonna be different. Volume 1 has a lot of great songs, but volume 2 has a lot by ennio morricone, who composed the music to all of Sergio Leone's movies. They both have great movie excerpts. But, Kill Bill volume 2 is the only movie QT has done that isn't rated R, the soundtrack only has that parental advisory notice on it because of the rap by the RZA after the urami bushi song. volume 1 delivers to a more matured audience of listeners, so i enjoy that one more...either way, they both kick ass.
