Wcc looks like a bi-modal distribution with a few very good teams and a few very bad teams. 6/10 are in the bottom half and 2/10 are in the bottom quarter.

Mwc looks much more like a normal distribution. 4/11 are in the bottom half with not have a single team in the bottom third.

Conclusion: WCC is much harder to be champion, but easier to have a good conference record. MWC is a conference where a team that clicks could take the championship in any given year.
