Hi,
this point is really interesting for me.
Is this true, that the Microsoft compiled code is faster and "better"? 
What does "better" mean in this context?

Also since I am not a friend of the newer versions (2005 and 2008) of 
Visual Studio, is this also the case for VS 2003?

Thank you for sharing your insights in advance,
with best regards,
Oliver
