I work with a product that has to use Philips head for one specific area. I hate those damn screws. They all need to be torqued to a specific value and this requires putting an significant amount of force axial to the screw to keep the driver from slipping. If you do slip, you'll probably strip the head and now it needs to be replaced. It doesn't help that there's a gasket around the plate that adds extra running torque. Good luck getting a countersunk #2 screw out. The rest of the product uses hex heads so those are incredibly easy to install.
