> 2) Unncessarily complex data model

Hmm? It’s just a directed graph of SHA1s under the hood. Seems pretty simple to me once you understand that. My understanding was that Hg’s data model is actually way more complicated with more pointers.

As everyone else is chiming in, the reason git won was speed. I haven’t used mercurial in a few years but at the time when I was looking to replace SVN, git did everything seconds faster than Hg which made it the clear winner.
