GitHub is popular because it allows developers to connect the tools they want to use to their repository. Some people find having everything in one package convenient, but the truth is there are better tools for most everything GitLab does. I don't see how jamming everything into one application makes it appealing.
I prefer GitHub's approach of allowing applications to deliver more information back into GitHub https://blog.github.com/2018-05-07-introducing-checks-api/ As the tooling we use becomes more complicated that will be the winning strategy.
