Though it has no clear commercial counterpart (Adobe Pagemaker? QuarkXPress? Adobe InDesign?) (La)TeX is far superior to any rough equivalents for document production. For text manipulation (including editing), GNU Emacs (which also was superior to and eventually beat out commercial Emacs like Gosling Emacs [ https://en.wikipedia.org/wiki/Gosling_Emacs https://en.wikipedia.org/wiki/Gosling_Emacs ]) is far more powerful than any commercial offerings. As an operating system, Linux seems to be well-established as the server and scientific/supercomputer OS. Maybe OpenZFS over commercial RAID offerings?
