In addition to the other answers posted here, I would choose C# over VB because C# programmers get paid more. More experience with C# = more $$ :)

I know both languages are almost the same and its really easy to switch between the two, but I think when management looks at a bunch of curly braces and semi-colons they accept the fact we are doing something they cannot do, where with VB.Net they might look at it and go "oh that must not be that hard to do if I can understand it".
