How SonarQube is better than the ReSharper,Fortify and the code analysis features that Microsoft provides?

In my organization, I have to convince the higher management about using the SonarQube throughout the company. So can someone list all the points which make SonarQube standout from the tools like ReSharper,Fortify etc. and the code analysis features that Microsoft provides?
Why as a company which is a complete .NET shop should go for SonarQube?
