end the argument by presenting the numbers. win/loss record, yards, attempts, td's ints and qb rating.
then take in the coaching situations at both paces. who dealt with differt o cordinators and what injuries were involved and i think the actual play over 3 yrs will plainly set forth the better qb.
but for the record, the niners are getting better while the raiders are not, and wont be any time soon. can we base this on qb play? maybe. the raiders have "the best cb in football" while the niners have the " best lb in football" there are a lot of similarity's in both teams. but in the end, wins count. stats dont mean shit.
