In my experience, the problem is not the way the reviewer/reviewee relationship is framed, but more about ego spoiling this relationship. One of both think they know better / have more experience or leverage, and that they are entitled to accept or reject as they see fit. The other person (no matter if they are reviewer or reviewee) gets frustrated. The result is that quality does not increase.
