I cannot be very objective here, as I am working on the directly competing product, but previous versions of Intel compiler were *really* buggy. Compiler choked on complex integer code regularly. I think it behaved better on FP code because one FP code resembles other FP code much more than one integer program resembles other integer program. Some time ago they started to pay attention not only for the speed of the code they emitted, but for compiler stability as well, so recent versions were much better in that respect. Not sure what the status is now, and don't want to speculate.
