I'm not using it in production as I'm not cloud operator but I can say that it is stable and mature enough to use it.

In Red Hat OpenStack (RH OSP) it's default networking backend since OSP16 (based on upstream Train version).

Regarding list of the feature parity gaps You can check https://docs.openstack.org/neutron/latest/ovn/gaps.html - this list should be more or less up to date. In case of any doubts You can always ask on neutron channel on IRC about specific feature which You would need :)
