Is upgrading to NG Firewall worth it?

Hello everyone. I have been using Untangle for some time now, and I am currently on version 9.4.2~svn20130830r35759release9.4-1lenny. My question is whether or not I should make the jump up to NG Firewall or not? Are there any specific pros vs cons in doing so?

My apologies if this has been answered before. I did a search for it, and found no results, so I thought I would ask for some expert opinions.

Thanks, in advance, for any information you can provide :)
