I think I have some relevant experience here.
We host all of our projects on github:
https://github.com/sqlalchemy/
yet we also use gerrit!
https://gerrit.sqlalchemy.org/
users send us pull requests, and they never have to deal with Gerrit ever. We use a custom integration, the source code to which is here: https://github.com/sqlalchemyorg/publishthing/tree/master/pu... and then we mostly bidirectional synchronization between Gerrit and Github pull requests (code changes can move freely from Github PR -> gerrit, comments and code review comments are posted bidirectionally, Gerrit status changes are synchronized into the PR - example: https://github.com/sqlalchemy/sqlalchemy/pull/5662
I continue to find Gerrit's code review to be vastly better than Githubs. Gitlab would take tremendous server resources to run internally and I like Github much better for the front-facing experience.
I wrote about an earlier form of our integration here: https://techspot.zzzeek.org/2016/04/21/gerrit-is-awesome/
to sum up:
1. your project benefits massively by being on Github
2. Gerrit is awesome (for me)
3. gitlab is not very appealing to me UX-wise and self-hosting wise
4. you can still use pull requests from outside users and use gerrit for code reviews.
