Here are a number sites with performance comparisons:

http://computational-battery.org/Programvare
http://www.coyotegulch.com/reviews

I think that overall they support the idea that today
the Intel compilers (C, C++, Fortran) produce better 
results on average, but this of course is not a statement 
about a particular application on a particular node.
