Torx is better than whatever this Canadian abomination is. You’d only put pressure on the corners in a realistic setting. These would get rounded so fast unless they are massive, like on some differentials or gearbox oil drains.
Never had or seen a stripped Robertson, they are robust AF. Don’t ask me the physics. (They go deep into the screw head because of the simple shape, maybe that has part of it. And they are tapered, it’s not just a square, so they manage to grip the bit like a mofo. You don’t cam out of a Robertson.)

I’ve snapped so many Robertson bits in my life. Screws are fine.
1 5/8" cement board screws
They used to be Robertson. They switched to Torx.
Night and day difference
Like you said, they do grip like a mofo, and with an impact driver, the bits snap.
I tried dozens of different brands of bits. Even paid top dollar for special Milwaukee ones.
I was at a point where I had to pre-drill and counter sink the screws because I was breaking too many bits.
I could probably drive a torx head one through a board
Hex already fit that niche.
Torx was just so they could make wood screws that weren’t Robertson and it bled out from there.
Torx bits are waaaay stronger than hex. Like double the surface area and tapered to work when corroded.
My 30 year old VW axles with hex bolts were a nightmare. The new ones are all Torx or 12pt.
I ended to driving an oversized Torx but into the nearly stripped hex bolts to finally remove them.
