unless you two are both mixing the same basic tracks for the same song, there's no right or wrong, no better or worse. no logic. a million factors can affect the outcome of this shit: mood of the band, gear, competency of the band, different studios, different acoustic colorations, GEAR... and then you get into a lot of subjective shit. you mix different songs, i guarantee you: the results will be posted, and the thread will grow to 478 pages, with a lot of name calling & no clear winner (unless one of you truly does suck beyond imagination).
