Unfortunately there seems to be very little consistency in the stability of community and official releases. For 10.0 the community edition was seriously flawed and the final was pretty good. From all accounts the opposite is true for 10.1
I never got round to installing 10.1 Community, but I don't have any real problems with 10.1 Official. IIRC the 'problems' with Official that have been mentioned here are just that the commercial packages don't come on the downloadable distro ISOs but have to be downloaded separately, which is the same as with Community. Maybe I missed some other things that were reported though.
