Which free version is better from, Virtual Box or VMware and what package?

[Advice Pro]

I'm looking for:

ease of use
least maintenance
virtual memory
least resources use
no special hardware
no Internet connectiivity (I plan to run this in my basement)
must always remain free

I think this would be the VMware player.

use VBox easy than VMware and also stable

Vmplayer requires you have a vm image, does it not?
