If I may defend C#... I don't care for the MS platform, nor visual studio, but the language itself is very well designed IMHO. It's not flashy, nor sexy, but it gets the job done, and done well. I've written hundreds of thousands of lines of C# on OSX. I know when I pick C# for a project I am not going to run into any gotchas or rough parts of the language.
If C# has a problem, its how low its cognitive load is. The dumbest "programmer" I've ever met was able to call himself a C# programmer, and likewise, for some of the finest minds I've met.
That being said my preferred language is Ruby.
