When considering git vs svn for work projects, is Mercurial best of both worlds?

Question

Lately I've been searching for the best source control technologies for my work projects. I've been a subversion user for a while, but heard more and more about git. So I checked it out, and I very much liked the fact that it allows you to easily put your projects under source control, even offline, when you don't have access to a server. However in multiple programmer environments (for instance at work) the idea of a central server still has its benefits. That's when I came across Mercurial, this seems to me to be the best of both worlds, since you can just put your project under source control offline, you can pull push to other people if they put up a webserver, but you can also use a central server to push to and pull from.. Combine that with the fact that something like bitbucket.com gives you the chance to start a private free repository online..

So am I right in my thinking, or are there some important subtleties with these source control systems in a work environment that I fail to grasp?
