Context matters here. Emacs uses bzr because it is an official Gnu project, but it's buggy and increasingly unmaintained, so there are reasons to switch. Jordi seems to have some personal thing against Git, while ESR favors Git but is bad at interacting with humans. It's standard mailing list politics, with technical considerations irrelevant; IMHO the two most likely outcomes are sticking with Bzr and moving to Git, depending on how much ESR manages to piss people off.
