The drools platform has an incredible amount of features, the core is stable but as mark said new features and new bug fixes can only be found in the community release. I also think that the community answers pretty fast to critical bug fixes. So basically depends on your use case and in the amount of new features that you want to use.
My two cents..

Thanks Mark. 
Agreeing with you that the Enterprise release is clearly more stable, the question really is how stable is the community release? For instance, Tomcat's 'community' release i.e. the version downloaded from Apache directly is very, very mature and stable. We've run that for many years with hardly any problems. Is the Drools community release close to that? Would we face big risks going with it in a production environment? I should add that the environment is not a financial type of system and we can probably live with a little bit of risk.

Thanks again.

The commercial project code base is supported for 5 years and bugs are
patched without forcing you to include new features or apis. It's tested
against a wider range of projects and application servers and releases
are generally based on a given corporate schedule.

The project is released when it's ready and bug fixes are not
backported, so you always need to be running bleeding edge to get latest
bug fixes. So while you get the bug fixes, you also get all the new
features which haven't had much testing yet and can introduce some level
of instability. This puts a lot more onus, and thus cost, onto the end
user to test more thoroughly in their environments.
