Which is better C# or JAVA?

[Grant]

As you are doing C/C++, you should go for C# because your basics will be revised while learning. Moreover C# is faster to develop in (especially GUI design), has a better IDE then any of the various Java IDEs out there, can perform lower level operations (fixed statements and unsafe code).
