The major flaw with dead bugs is you lose the identification of the ic.

It's cheap and easy now to make a few double-side or multilayer PCBs

True but you can reuse a speedwire board :)

Yuk! I remember how awful WireWrap protos were. I wrote a PDP-11
program to optimize wrapping, the traveling-salesman problem.
I hated wire wrap but liked speedwire.
If it wasn't speedwire it was a soldering iron and what we called veroboard.
Non shrink-back ptfe wire was useful too.

One nice thing about PCB protos is that you can keep them around
forever, for future reference. Vias and ground planes and 50-ohm
traces and edge-launch SMA connectors are all good. A spare unstuffed
board or two is nice to have around too.

I often put several different circuits on one board, and shear them

What PCB design system/software do you use?

PADS. We've been using PADS since the DOS/floppy disk days.
Ok not one I've used.
It works
well enough. We use the same ever-growing parts library and can open
decades-old projects.
Yes I've had that problem. I think it was OrCAD which couldn't open older versions of its own files.

What's weird is that Digikey has cheap proto "redboards" now but claim
that they won't work from PADS files. Gerbers is Gerbers, I'd think.
