There are obvious outliers, but this guideline = survived from (at least) the early Apple UI tests through ~2001, when I = stopped paying attention -- but I'll be surprised if it's changed much. To the point, bazaar/git continues to be much faster than git/bazaar for = some operations and much slower for others. Neither is fast at all of = the `important' operations for all developers, and the architecture of = each suggests that these things are unlikely to change (although we can = hope for improvements to both, over time).
