I keep seeing posts about large organisations (off the top of my head, python and mozilla) consider bzr, and then discount it.
This mostly seems to be because of its performance.
Having used git and bzr extensively (and a bit of mercurial), I've found it's performance to be perfectly fine for general use on reasonably sized projects, and the ease-of-use to be far superior. Figuring out how to get Bazaar to do something you haven't done before is much easier than trying to track down a Git feature. Although I will admit that Git is improving in this regard, while Bazaar continues to improve it's performance and focus on interoperability.
Anyway, in summary: I really don't get why more people aren't using Bazaar.
