OCB means Odoo Community Backports. It's a voluntary work to fix bugs and security breaches in Odoo versions that the Odoo company does not maintain. As such, OCB should be your preferred Odoo version. OCB versions are supported as long as there is someone to do the job.

From time to time new Odoo features may be backported. These features are selected to not break current modules workflow.
