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.
Indeed torx is so good because it attempts to maximize the surface where pressure is applied to. This is good on smaller sized bolts that are more prone to being rounded, but especially amazing when removing bolts that may have been exposed and potentially corroded
Yeah, hex is very nice but torx is improvement over it.
I have not checked on it, but I'm like 97.25% sure wood screws jumped from Philips to torx however because of corrosion resistance. Hex is very easy to round already as is on smaller sizes, but even more so if the head is exposed to elements and corroded. Of course material matters a lot, but even stainless corrodes over time.
Torx has to be very, very bad condition for it to round, it's more likely for the screw to snap
Sorry for drunk rambling but I really like bolts. And bearings for what it's worth
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.)
The internal hex on sway bar end links are useless after any time in the salt. Last time I had to remove them I went straight to the angle grinder and ordered a new pair. Didn't even attempt it.
