I definitely agree about VS. Microsoft got a bunch of heat for VS2012, but it's been their best release yet. Their IntelliSense support for C# is unmatched by any other language-IDE pairing I've used.
That said, I've used MonoDevelop in Windows and OS X and it works pretty damn well. The Mono project has done a great job mirroring the .NET API and runtime.
