DV was everything a UI should be. Incredibly fast and responsive. Keyboardable for everything. And it stayed the hell out of the way unless you asked it for something. It unlocked the potential of the 80386, and finally gave us the multitasking we'd been promised for years. Better yet, I could use all my same software; it successfully merged my single-purpose DOS applications into a multi-purpose environment that I could use for every aspect of my daily tasks.
Windows was a sorry joke in comparison. The DOS experience on Windows was second-class, and terminal software for Windows was never as good or as flexible as Telemate. I only begrudgingly installed Windows because it was required to play with all this "winsock" software I'd been hearing about, since I had no clue how to set up TCP/IP on DOS. (There might've been tutorials in places I didn't know to look, but Windows advice was everywhere.) And single-session BBSing was rapidly going the way of the dodo, so with it went DV.
The irony here is that DV/X would've allowed me to do all the things Windows was offering, probably in a better way, if only I'd realized that at the time.
More's the pity.

There were other ways too, but i found that code so valuable several times

So, Wildcat! or PC-Board?
I think Renegade's non-warez scene competition was TAG, WWIV, Wildcat and (of course) Telegard. I kind of liked all of them for various reasons!
Edit: my first BBS ran on an Atari 800XL with software written by Jeff Minter. Had to hack up a ring detector for the lame Atari 1200 baud modem. Lol!
