Mandrake 10 Community vs. Pro

What's the difference between the two? Is it worth the upgrade? And if it is, which is better, doing the upgrade, or a clean install?

Community was a beta version really. Official is better, but still can have some issues on some machines - ie rock solid on some, slightly glitchy on others, crap on a few.

So what's the better way to install if assuming you have the Community version already running? Upgrade or just clean install over it?
