We ended up with mercurial. We needed Windows, Linux, OSX and code in all kinds of languages.

git is fine I suppose - but we needed to support Windows and I'd rather know that Windows is supported properly (mercurial), rather than kinda hoping it works (git). Things might have changed since the last time I looked.

In either case, be careful with case-sensitive/non-sensitive file systems.

Also, consider the learning curve difference as you will suddenly become the go-to guy for issues.

In the end, I'm really a Bond fan: http://importantshock.wordpress.com/2008/08/07/git-vs-mercur...
