Clutch settings are worthless unless the substrate and the sheathing are of consistent density. Drywall can be considered consistent, and drywall over metal studs would be a consistent density substrate/sheathing combination.
However, drywall over wood studs (of any species) is at best a hit-or-miss proposition. Get the clutch set just right for one screw, and I'll bet within a few more attempts, you'll find a spot where the clutch doesn't disengage and you overdrive the screw (lower density wood beneath), or the clutch engages too soon and you can't seat the screw (higher density wood beneath.) Of the two, the 2nd problem is more irksome than the first. One can always stop the driver when the screw seats. If the clutch is engaging too soon, there's no choice but to adjust the clutch to get the screw to set.
Even steel studs are no guarantee - if the screw is trying to penetrate a double layer of steel, as at an intersection, or if there happens to be solid blocking in the studs for cabinet hanging or other structural requirements - trouble looms.
McFeeley's is now offering Robertson drywall screws. They even state that really Phillips are better in this application, but people are asking for Robertson drywall screws, so they're delivering.
Personally, for me, it's Robertson all the way, except when I'm hanging drywall, then it's back to Phillips. I've completely given up on the screws available from my local big-box store. I recently tossed a really old box of #10x1.5" phillips-headed screws. Even when driven into a properly piloted hole (and I have the kind of pilot drills that are tapered to match the profile of the screw), about 2 in 5 would strip before seating fully. This is when using a quality new phillips screwdriver of the right size. No way I would have even tried to use my impact driver. One box of 50 screws - happily thrown into the waste bin...
I have found that the experience of using Robertson screws is enhanced by making sure to use a good quality bit, and change it when it starts to wear down. However, that statement holds true no matter what your preference is for bit type.
Torx are the domain of the automobile. I've run into them on occasion in wood working - always pisses me off. Of course, if I ran into a Robertson screw while working on a car, I'd probably be ticked then, too.
