Disagree. It's gotten better, but the tooling is awkward, the commonly used UI (TortoiseGit) is wonky, and not being a "native citizen" on the OS isn't acceptable--MSYS is a mess to have around on a Windows machine and even the "minimal subset" that you can install with Git is more than I consider acceptable. (I realize that entirely too much of Git is UNIX-based plumbing, but that's their problem.)
I gave Git another shot when Bitbucket started to support it (I won't use GitHub, as it happens), but it didn't shake out for the above reasons. I like being able to open stuff up on any of my machines and the lack of care I perceive in Git on Windows drives me to stay with hg a lot more than it would otherwise.
