i think soundgarden were a little bit more technical as pj, eddie and chris are both very well singers, eddie's voice is more wrapping, maybe chris reaches better higher notes...pj are more melodic, that's clear, but i think soundgarden express the grunge style in a better way, and by the way we can say that soundgarden invented grunge, (they came before nirvana and pj) pj are still around, but in the last record they didn't reach their highest level, like ten, vs or yield...i love both bands, i'm listening to them almost every day, so that's why i'm interested in your opinions
