I haven’t used TFS so much. But I like it so far. It works smoothly, both TFS 2012 (on premises) and TFS Preview (online). I really appreciate that Microsoft has been inspired from git - the world’s best VCS :). For example .tfignore which works exactly like the .gitignore file. It is nice that the non-classic Microsoft dot notation convention for naming the hidden files is chosen. So if you have any files to ignore just do it like you did in your git projects.

Until now I have only worked with svn and git. So I am very curious about the Team Foundation Server and Team Explorer which all talk much about. The best thing is the integration with the issue tracking. I can see all work item, or just my work items. Another fine feature, at leat if you use codeplex, is the Team Explorer Everywhere. The Team Explorer Everywhere client works on Windows, Linux, Mac, or Solaris.
