Are you having problems with cam-out damaging the screwdriver, and then
the screwdriver in turn then damaging more screws? If that's the case, you
might try the Klein brand philips screwdrivers with hardened blades. They
are made for heavy daily use and abuse and don't seem to wear quickly from
cam-out, making them a lot more resistant to damaging screws due to wear
on the blade causing even more cam-out. With cheaper philips drivers, once
the blade begins to wear even a little, cam-out becomes a bit of a
run-away condition with each additional fastener you use it on.

The reason I asked about this is because I'm getting increasingly
annoyed with philips screws. On the other hand, if you don't need the
cheese or button heads,
McMaster has T15 6-32x1/4" pan head screws for 6.22 per 100,
which doesn't seem like a terrible price to me. Aside from some
visual finish, what's the advantage of a button/cheese head?
If you're working on a piece of older Compaq gear, the cheese head is
part of the slide-in mounting system for the disk drives. That is, the
cheese head forms the protrusion that slides in the groove of a plastic
guide.
That being said, ordinary slotted cheese-head 6-32 screws will work
fine--the only thing lost is the Torx feature.
HP also used some Torx-washer-head screws on some of its hard drive
mounting kits.
