FWIW, I recently transferred my side project from bitbucket to gitlab and I'm really happy with it. The issue tracker is significantly better, and the built in CI seems great but I haven't started using it yet since I already have codeship going.
The response time on gitlab.com was painfully slow. That extra 2-3 seconds waits for each commit was enough to drive me back. I still use github for professional projects and bitbucket for personal ones.
I hope you're willing to give GitLab another try when we've improved the performance of GitLab.com or by hosting it yourself.

I pay for GitHub and enjoy it.
