Going from an Openbox V8S to a Vu+ Zero.. What will I gain?

Hi all,

I'm upgrading my cheap and cheerful Openbox V8S receiver to an Enigma2 based Vu+ Zero. In terms of unlocking feeds, is there anything I would be able to watch/unlock that I cannot do currently, using an Openbox?

Any advantages/disadvantages would be appreciated before I click 'Buy' :)
