I am the opposite way. In my experience usage of signed where the underlying type is conceptually unsigned introduces subtle bugs. Whereas the defined behavior of unsigned wrap usually causes very obvious stalls and overflows. I have seen so many array access of -1 which never SEGV until you upgrade your compiler or change platform. Also pointers are typically unsigned, I suspect same-type operations are faster for array access... though I never have checked.
