I would have given my vote for Plesk because it works irrespective of the Operating System. However, I vote here for cPanel because of its easiness, reliability, regular upgrades, functionality and many more.
I heard that even cPanel is about to release a control panel that would support Windows OS. They named it as "Enkompass". I think cPanel is not one of the best control panels but it is the only best of all control panels
