I've been using patchwork with GCC since, roughly, last year's cauldron. Its main weakness is a poor search function for finding relevant patches, which means that since most patches in the queue aren't being managed it's a bit hit-and-miss finding the relevant patches.

Its other problem is that it expects a particular workflow model, particularly not replying to an existing patch discussion with an updated patch (it expects patches to be reposted as an entire series with a new version number, Linux-style).

But there are some benefits to using it: I can integrate it with my mail client - it can show me the patch series in patchwork when I receive a mail directly; it integrates well with git with the git-pw module, so I can pull an entire patch series off the list into my worktree from the command line just by knowing the patch series number; and I can manage/track patches in bundles, which is great if I don't have time in any particular day to deal with the email volume.

Finally, it's been integrated with our CI systems (thanks Linaro!), so it can automatically pull reviews and run validations on them, then report the results back; often before I've even had time to look at the patch.
