I administrated an instance of GitLab EE for around a year solo for my previous employer. It was absolutely painless. The biggest issue I recall hitting was when I upgraded my LetsEncrypt setup broke, because they added LetsEncrypt setup to the core. The bug that caused it was fixed a couple days later anyways, though.
We used GitLab CI very heavily. The only issue we hit was disk space on workers filling up - but it was easy to resolve this by making a Cron job run `docker system prune`.
Generally, the GitLab team definitely has moved very quickly on new features and that has caused things to break here and there. I also agree they could use better regression testing. Still, they are very responsive to issue reports and most of the time issues that I care about are resolved very quickly.
GitHub as a competitor obviously is a lot more stable. But, I was definitely willing to trade some stability for the features GitLab offered, and I do feel they have been steadily improving in the past year.
