You Control: Desktops free preview; best desktop manager?

You Software Inc., makers of the You Control menu utilities, is working on a desktop manager application called
You Control: Desktops. They are inviting OS X users to download a free public preview of the program, which allows you to create multiple virtual workspaces.

Hopefully I will have time to check this out myself, but if anyone gets there first and feels like posting a review,
please comment. Which leads me to the bigger questions: do you use a desktop manager application and if so, which one?
How does it compare to others you've used?

I started out using CodeTek Virtual Desktop but eventually figured out that a text-entry bug I kept seeing in Firefox was being caused by interaction with CTVD. Since the bug effectively rendered Firefox unusable, I tried switching to Desktop Manager and have been very happy with it so far,
even though it's officially 'alpha' software.
