Can you help me out?

I have a Samsung Galaxy S II running CM9. I really like ICS, I'm thinking about selling my SGS2 and buying a Galaxy Nexus. My problem to decide is the following:

SGS2:
+ Better Camera
+ Better GPU
+ Micro-SD

GN
+ Better Screen
+ Better support (up to date, better community, more open, etc)
+ Faster Camera

Is it worth it?
