Which is the best git hosting sw? - Gitolite vs. Gitlab vs. Gitorius

I am looking for a git hosting environment for several users. Therefore i've searched for comparisons between Gitolite, Gitlab and Gitorius. But i get nothing what could be useful.

Is there anybody, who has experiences with different hosting tools and could provide an advice?

• Gitolite is not a git hosting environment: it is an authorization layer, which grants or denies access to a git repo.
  It is the https or ssh layer which allows the authentication of a user, and the git repo hosting itself.
  See "How do programs like gitolite work?"
• GitLab and Gitorious both provide git hosting, with (to my opinion) an easier installation process and more features for GitLab.

When comparing GitLab features and Gitorious features, the issue tracker is more complete, the fork and authorization levels are present, GitLab has teams and groups, webhooks, and API.
The development is more active (one release every month) on GitLab.

Update: GitLab has acquired Gitorious
