But, be honest, git was better than mercurial as well.
And the reason that it's better is that the support is universal (now). Even back when the battle was being actively waged between git and hg, the popularity of git made it a better choice for pretty much everyone.
Yeah I know, that's the problem. In other words, many of us decided git is the best because many of us didn't know any better.
But it's been more than a decade, surely that's enough time to reevaluate one's position.
