Nexus 7 2012 and Nexus 7 2013

I have posted a similar post in the tablet talk forum but more people seem to use this one:

Is it worth upgrading my 2012 N7 to the 2013 N7?

Mine works pretty fine at the moment but just wondered if anyone else has done this upgrade and what their experience of this was- - good/bad/not really much difference etc etc...

Thanks guys
