Agreed. Gitlab's interface is better. Especially the issue board. Throw in their fully-integrated CI platform and container registry basically makes Gitlab a winner.
I'm using both Gitlab and Github for different projects, and I just can't stand Gitlab's interface. Informations are scattered all around the place and there's no distinctive way of finding the information you want. Plus it's slow as hell. Github's UI makes sense. I can find anything in the blink of an eye and it's blazing fast. The team I'm currently working with is completely fed up with Gitlab.
The Gitlab UI is /fine/, but the speed is what gets me. On github, even if I have thousands of commits, the UI is instantaneous. If I click on something, the load time is less than a second for me. So I switched to Github and paid for the private repositories. I absolutely didn't mind paying for this since Github is so fast for me and seems to be adding pretty cool new features (code review enhancements on PR, for example).
I still have one of my repositories on GitLab and it's still slow when I do things like browse commits, view source files, etc.
It's not just Gitlab though. Bitbucket is pretty slow for me as well, though not as slow as Gitlab. I would guess that Github's caching algorithms are much better than either of those two to really make pages seem snappy.
