Company A, without a doubt. Culture matters a whole lot. And the experience of seeing how one of the behemoths does it from the inside, good and bad, is valuable. (Don't have any info about your job history; this last point could be less important if you've already had that experience.)

EDIT: I typed 7% earlier instead of 75
