Well, if you treat git as Torvalds intended it in the beginning (framework for building VCS-es) and accordingly limit the discussion to git's plumbing command set, you get a sensibly good UI+architecture that is targeted at programmers that write VCS-es. Git being operable with a pry bar and repairable with a hammer is a good proof that in this context it's a good design.
