How you do PRs is definitely important, and should be part of a company's consideration here, but remember that PRs are already a layer of abstraction over the SCM. Self-hosting Git is definitely not as easy as setting up a GH account.

Not to mention that you get an easy way to spin up your CI/CD workflows in GH Actions (which of course definitely has its own problems, which there was another popular HN post about recently). There's a reason why it's the default for new companies -- if there was something much better, it wouldn't have the market share it does I think. Familiarity coming from OSS is also important.
