I've also tried the 10 user licenses for both Jira and Bitbucket servers. I absolutely loathe Jira. I respect its vast featureset, but user experience as a programmer has felt absolutely abysmal. The React redesign only confused me more. To find the Kanban boards, you had to hit the search button! I hope Jira has improved since last time I used it, but I have to say I'd probably prefer just about anything else at this point.
As for Bitbucket.... It works, but I can't think of a whole lot it does that GitLab doesn't do better.
