I bought SublimeGit a while ago, and have been reasonably happy with it, but this looks much better (and has many of the features I would have wanted from sublime git).
I have been using it consistently over the last while, and I was reasonably confident of completeness and robustness enough to call it ready to share. That being said, there may be bugs in some of the darker corners. I'm pretty happy with how it has turned out so far, and I'll be watching for any issue submissions.
