I like GitLab and GitHub quite a bit, but I lean toward GitLab for the simplicity of a unified tool chain.

However, I think GitLab can only really shine when you host it yourself. In 2020, on-premise/self-managed anything is kind of a hard sell, but the reliability and performance of gitlab.com leaves a lot to be desired. (So much so, I often think about trying to work for GitLab so I could help from a reliability perspective.) I stuck my neck out for GitLab in a previous organization and we ended up migrating from github.com to gitlab.com. This set me up for some embarrassment for every outage they experienced last year which felt surprisingly frequent. But if you have the resources, self-managed GitLab is great!

tl;dr: gitlab.your.org > github.com > gitlab.com
