Mercurial was pretty close to contemporaneus. And when git was first launched it was extremely bare bones and even more incredibly hard to use than it is now. Darcs, Monotone, and Arch were slower and I think predated git. Darcs in particular blew the doors off of git as far as ease of use given the problem domain.

Git won almost entirely due to two factors.

1. The linux kernel used it so that brought some prestige.

2. Github made git hosting easy and free for a lot of people and had the cultural cachet to drive adoption.

Git has a very solid underpinning. But it's user interface and lack of guard rails has always made it painful. People endure the pain because if they don't they won't be able to use the tool that their industry has chosen. But some of us wish a different choice had been made in the dvcs arena.

It's also important to remember just how far Git was ahead of most competitors in performance. I was using monotone quite a bit around this time, and while its UI was frankly not much better than git's, it at least worked acceptably quickly. Darcs was mostly defined in the public eye by the exponential merge issue. Hg was fine, for some definition of fine, but it was enough slower than git to be annoying -- maybe not deal-breaking, but noticeable on pretty much any task.

I remember installing cogito to act as a front-end for git because very early on it seemed obvious that (a) git was going to win, and (b) it was going to win in spite of its UI, which was saying something.

Darcs was easy to use? Are you referring to the same darcs whose manual tried to explain concepts by making analogies to the simpler and better-understood theory of quantum mechanics?
