I was a DR-DOS 6.0 user and it was great, 7.0 seemed to be worse. But by then I had moved to Coherent then Linux when MW closed down. I will need to give DR-DOS a try.

And then there's PDOS (public domain operating system): https://www.pdos.org/

I remember a couple of friends using DR DOS in the 1980s. There seemed to be a disagreement about whether to pronounce it as /di ɑɹ/ or "doctor". (I realize it was named after a company and not after a doctor, so the former is more etymologically faithful.) Was there a standard among the creators or the user community?

I used Novell DOS 7 back in its day and squeezed > 70 MB on my 50 MB hard disk drive thanks to its Stacker disk compression feature. I remember it coming in a flashy red colored box. It also supported to move most drivers into extended memory to have much more conventional memory available on 386 machines. However, most cutting edge games used DOS protected mode extenders already, so for gaming you couldn’t use that feature. Great times, anyways. ;)
