The only good thing about slot screws is that you can use any reasonable flat thing as an emergency screwdriver. And the screwdrivers can serve as a general purpose prying tool I guess. They suck at their official job.

I am constantly camming out cheap Phillips head screws and it drives me crazy

The problem is that manufacturers keep using Phillips screws for high-torque applications.

Just this week I nearly stripped a drill bit installing some curtains and the manufacturer had supplied some Phillips wood screws. I had to keep my entire bodyweight behind it to stop it from camming out. Phillips wood screws shouldn't even exist. They won't even stay on when you put them at the end of your drill. I ended up throwing them away and used my own Robertson screws which went in like a charm.

All of this based on the assumption that people would overtorque fasteners if you didn't use Phillips screws, completely ignoring the fact that this isn't a notable problem for the many manufacturers who use Torx or Allen screws.

Anything Philips can do, Torq can do better. There is already a simple method to prevent furniture damage or any other rare instance where you want the screw head to slip : use the correct sized screw and dont over torque it.

Roberson was also a Canadian, so you're fitting along well in uh... your screw preferences too!
