3D: C# vs. Java

HI
I have to program a 3D helicopter simulator. I'm asking what would be the better decision for that:

C# with .Net or Java ?

Thanks for suggestions!

i would suggest C#.NET since you can interact with reusable lowlevel win32API and/or COM dlls , or user dlls, in C#.
Java would be slow .anyways.. :D
