1. Both tools are good enough. Source control is an engineering practice. Good enough is the core of engineering. 2. Source control was and is an expanding market. Beginners don't have the experience to make informed decisions about ergonomics and other nuances. More or less the features of git vs mercurial don't matter when a person adopts source control for the first time. 3. Ecosystems trump ergonomics...e.g. github. So does branding...i.e. the software Torvaldes wrote. And if I could make a bet, I'd bet Torvaldes writes software about as good as anyone on the Mercurial team, if not better.
