I think hex is superior to both as it’s way harder to strip than a torx and it has 50% more options for starting angle than a robertson, which comes in handy when you can only get at the bolt head from a right angle, while being almost nearly as grippy and strip-resistant. Plus it’s presumably simpler to machine than a torx star.
The biggest problem I have with hex drives is that there are far too many sizes, (in multiple systems!) meaning you have to carry dozens of bits, and using a size that’s just a little too small creates a huge strip risk.
Robertson and Torx both use a comparatively limited number of sizes, which makes the logistics way easier.
