I'm trying to figure out which of these two Windows control panel is better:

Parallels Pro Control Panel (formerly known as Ensim Pro)
Parallels Plesk Panel

Can you guys tell me which one is easier to use, is more powerful, etc?

FYI, I'd like to open up a reseller program with this panel.

I would suggest Plesk panel for its stability, security through its rich features and its easy to use.

But it's so expensive, at $1499. Is it worth it? Or do you guys just pay the monthly fee option instead?
