Speed and workflow, previously. Mercurial has made up most of the difference in speed, so now git is better for some things ([temporary] topic branch workflow and history clean-up of such branches before merge is more likely to be used by git committers even if hg technically has that now, speed in a few cases, mindshare) while mercurial is better for other things like syntax, or dealing with gigantic repositories -- like Facebook's[1], but only because Facebook engineers decided that functionality was easier to add to mercurial than to git.
