Torx is a lot less likely to strip out the tool or the fastener than Allen, especially at smaller sizes. Torx comes in a smaller variety of sizes than Allen does, so it’s more difficult to choose a slightly wrong size. Especially with Allen being offered in both metric and moon landing fractionals, there’s like, M0.8, and 14/93", one of which fits slightly loosely in the other and will sorta work, until you turn real hard on a stubborn bolt and round out the screw and/or driver.
In other words, it is my experience that you’ll have a large pile of allens that you can’t realistically tell apart, and a set of like 8 Torx tips from which you only use like three.
Also, M1.5 hex is getting a little too close to a circle, and you can forget about going much smaller. M1.5 torx is still usable.
Also (for the same reasons) Torx heads don’t have to be as deep for the same torque as an Allen. More space efficient.
