I disagree with the idea champions>masters. The additional 4 teams that attend champions don't make winning the tournament significantly(or even much at all) more difficult than winning masters. Also, I don't think the achievements listed make them pretty equal. In my opinion, the optic core definitely have the edge with showing such consistency over such a long period of time.
