Already my own experiments suggest that LLVM is a superior compiler, by every metric I know of, I know OpenMP/Clang, but as far as I know OpenMP is not upstreamed in clang yet, is it? If not, it's not superior yet in scientific computing :). But it will happen soon. And at the very least, LLVM's approach has created a large ecosystem that gcc did not have.
