Thanks for this good article. I took a 15 minute tour of both HG and Git and felt that hg was overall a better experience, but felt if the community is moving towards Git there has to be some good reason. I'm always a fan of the underdog, so I've been asking everyone why Git (besides Github of course).
This is the first article that gives real pitfalls of one vs the other. I enjoyed the read and would love to hear more as well as counter arguments.
