Being an active user of both git and hg, I also can't think of any features I make extensive use of in git (rebase, feature branches, etc) that I can't get with hg. My workflows in both are pretty much the same, just a saner interface on the hg side. If anything, git doesn't have revsets, a really powerful query language you can use to sift through your history - see http://www.selenic.com/hg/help/revsets
