How about Music players, Sequencers, studio, DJ, Drum machines, Guitar software amps, software radios…
The fact that you simply ignored music players disqualifies your list. Also considering that Arch’s AUR, for example has over 90.000 packages, the idea of one person compiling a useful general “best of” list is deluded and doomed from the start.
I don’t write this acrimoniously, I simply state the fact that unless you enlist help (and a lot at that) your endeavor is useless.
Corel was, and still is, used in a lot of industries, like signmaking, embroidery, etc. It has been losing share in the general vector graphics space for years though.
