I used to work with some folks who believed the Intel compiler was amazing. I think the logic to the myth was, "Who would better know how to optimize for Intel chips?".
However, in my experience icc crashed more than any other compiler I've ever used (internal compiler errors). That kind of a bug in a compiler makes me really wonder what else is wrong under the hood. And of course, being closed source, I can't possibly know...
