So it seems that availability of git is a strong argument. I also like the (unpacked) storage format though naming files by their hash.

Git status is also very very efficient (maybe it uses tricks with mtime), and git push/pull of large repos plays nice with bandwidth, such as the way to compare remote with local status (just compare a single hash for master for instance).

These few facts might quickly lead one to think "yeah, git's the best all of the time". Thanks for proving it false, nothing beats go checking the facts for building an opinion.
