The only aspect I would be iffy on (mainly because I've never looked) are the things you get just for being a Red Hat subscription holder. These are the Red Hat hosted services, like the Customer Portal and Hybrid Cloud Console (Insights, etc). But the actual products you get from the subscriptions? Yeah, those are all open source software with available upstream. As for value, the hosted stuff is actually pretty cool and helpful for getting proactive analysis, suggestions, alerts, etc of your environments. In general using the Red Hat product over the upstream provides a handful of benefits. Usually the software is pretty well stabilized, you're not getting random updates that require massive changes. Deployment can also be easier than upstream, or at least better documented. For example, deploying and maintaining AAP is a breeze, and can be done on traditional servers instead of k8s. It provides all the disparate pieces in one place, rather than needing you to deploy AWX, Galaxy-ng, Pinakes, Keycloak, etc on your own manually. The other non-software pieces, like the knowledge base, discussions, docs, hosted apps, etc are all effectively bonus material of a sort. But they are really good bonus material to have.
