I have used hg for about four years now and have basically transitioned over to git. It's hard to explain why, exactly. Yes, network effect, but it's more: it's like git integrated deeply into the underlying model rather than trying to abstract over the model.

I would call myself a power user - I am the clearcase->hg transition guy in what I do, I've designed/maintained an enterprise hg extension (guestrepos, look 'em up, they are amazing), use mq, etc. But I think that the fundamental win for git is that they don't abstract, and this allows clearer understanding of what is happening when things go pear-shaped.

But, that's my opinion. I use both on a daily basis.
