After I switched over from Eclipse to Intellij I think at least the IDE tooling is pretty much equals nowadays. I used Resharper in VS so in many ways you are using the same thing.

As others have said the open source community for Java is still leaps ahead of C#. It's not often you find a library which doesn't have a Java connector/implementation. For C# on the other hand you tend to be much more limited in your options.

I guess this used to be a lot due to the platform dependence of C# (and probably still is). Hopefully .Net Core can help with that, but it's not ready for prime time yet IMO.
