I'd say stick with what works for you. Unless you are having issues with VSS, why switch? Subversion is swell, though a little sticky to begin using it. TFS is far better than VSS, though it is fairly expensive for such a small team. I have not used git so I can't really speak to it. |

I could go down the list of features and pretend like it brings a lot to the table that other source control systems don't, but there's tons of good ones out there and the right choices is really a matter of style.
