2) Not s1mple's/NAVI's fault actually. Valve rules force Navi to play only CIS RMRs. They aren't allowed to play EU RMRs. This implies that RMR events will probably be ignored for both, or considered for both. In this link, I have considered EU RMRs (against EU opponents) but not CIS RMRs. That's why it seems Zywoo has played more maps. Otherwise, they're both the same.
3) Correct.
Conclusion is not so easy. Logically and statistically, I would say Zywoo>s1mple at the moment, but it's very very close. It can change by the year's end.
