The type of screw doesn't matter as much as the quality of the screw.

Certain types of screw drives/heads are more appropriate depending on application, and some are more prone to stripping than others are, regardless of quality.

I was going to suggest Robertson as well, but decided not to since I have never had the privilege to use them myself. All that I know is that after using Phillips for my entire life, I was thoroughly jealous when I first read a description of Robertson screws. Ford liked them to, he considered using them on his production lines to improve efficiency but couldn't due to their limited availability in the US.

You wouldn't be referring to clutch head bolts, would you?

I completely agree. But you can't forget that a screw or bolt of poor quality is more likely to strip out than a screw of good quality. Basically, the universal rule of "you get what you pay for" applies here. I would much rather spend a couple more bucks on a box of USA made alloy steel or grade 8 bolts than a box of no-name junk made from unhardened steel.
