Dear Salmaan,
In my point of view here in India C# is more popular than VB.Net. Becasuse most of the Java and C/C++ professionals would like to work in C#. Because they can ease to understand and ease to use C#.
Someone link VB.Net Natural style and someone linke Professional and terse C# syntaxes.
But both use the same Framework and speed is also very much equivalent.
