Compilers do better or worse depending on the code that you give them. 
I'm not aware of anyone who has done any thorough comparison between VC 
and LLVM codegen, but even if they did, my suggestion would be the same: 
I'd try them both out on your code and measure them directly.  You care 
about how LLVM does on your code, not how it does on some abstract code :)
