Torx and Torx Plus are superior drive styles compared to conventional styles that they replaced. The increase in surface area between the sides of the driver and the drive hole is significant and produces higher torque transfer to the fastener head near zero cam out.
If you were to replace the Torx with Allen or Phillips drive, it becomes apparent instantly why it is used. The main reason for any Torx related issues is almost always related to issues with high surface area contact under a flat head and/or the wrong size driver being used. If you are using a bit to remove a painted fastener like on the tailgate and you don't have to tap the bit in with a hammer, you are likely using the wrong size which will lead to problems or compound them.
No one who uses Torx drive construction fasteners ever says anything except "why did it take them so long to come out with these?".
Until you take a 4" long screw and run it into a wood beam standing on your tiptoes using one hand and a small impact driver, it will be hard to understand just how superior they really are. Another reason is they are low effort to install on the assembly line and will keep the worker from being fatigued which leads to stripped or ruined installations.
