I may be introducing the subject only to myself if this item is well-known. I encountered it in a reasonably concise Wirecutter article:
"Pros swear by Torx-head screws, an all-around better alternative to the formerly ubiquitous but flawed, finicky Phillips head... The cross-headed design of the Phillips screw is notoriously slippery and easy to damage. That’s why most of the rest of the world moved on from Phillips screws years ago, if they even adopted this miserable standard in the first place.This isn’t a problem with Torx because the star-shaped head provides much better grip and stability... And all that extra contact between the screw and the drill bit makes it much less likely that you’ll strip the head (or ruin your bit) even if you’re blasting your tools at full speed... [the embed shows a Torx compared to a Phillips with a stripped center]... there aren’t many credible technical or legal excuses to keep using Phillips screws. The patents on Torx (and other Phillips-beating standards, including square drive) expired decades ago, so anyone can manufacture the bits and screws...An impact driver looks like a stubby drill, but it sinks screws into wood and other materials at breathtaking speed. (Even basic power tool starter packs usually come with one now.) That tool’s efficiency is often wasted on wobbly, damage-prone Phillips screws, so it makes sense to pair an impact driver’s extra power with a snugger standard like Torx.
For those interested in greater detail, the Wikipedia entry has information on the Torx' history, physics, and subtypes.
