If you're looking for the hosted version, there's lots of complaints about GitLab.com's performance. Bitbucket is quite excellent and integrates well with hosted JIRA too - I'd say it's arguably a better option than GitHub in many cases.
I've had good luck with self-hosted GitLab's performance in my small group, but I've heard tales of others who haven't, so try before you buy if you're doing that. The CI integration is really nice though and GitLab has put good work into that flow. It can also be the cheapest option and keeps you self-reliant if that's something that appeals to you.
