I've always felt the compiled openoffice faster than the binary one, but if it is not the case portage also gives you the chance of establishing per-package optimisations on '/etc/portage/env/' or in the paludis bashrc, so if one user wants an particular app to go faster, he can research about the best way to build this one. This way, the user can keep the very safe optimisations for the rest of the system and some -unsafe optimisations- for the packages he want. It is more about choices...
