Honestly, for the home desktop or laptop user there aren’t any. Most of the very best FOSS software, and some proprietary apps, are cross-platform. The killer app is the operating system itself. It’s less bloated and faster than Windows on equivalent hardware, contains no adware, no spyware, no forced automatic updates, no unremovable useless crap you don’t want, and above all is YOURS FOR FREE.
