I find delegates to be a very nice addition, though.
Poor documentation? Have you ever read the .NET docs? They are some of the best, equal to or almost equal to the java docs.
As far as the API, there have been a number of instances when I would want to try something new in C# and the task I wanted was very clearly named and placed in .NET. It was easy to find. That happens less often in Java. It seems to me that Java has the API that may have been written by children.
I work with both C# and Java on a daily basis. I''ve written games in both. I can personally say that, at the end of a project, I am much less annoyed when I''ve been using C#.
So this thing goes both ways, yes?
(NOTE) This in no way is meant to bash C++, me love da C++ also
