The screwdriver slips out of the side of the screw as you turn it. They can be extremely frustrating.

At that point, make a second groove for a cross head and saw the tip off a Philips driver. That way, it doesn't cam out easily or slide out the side.

I think Phillips would look fine, especially if it's painted like those screws always are. And there are still other solutions, for example square drive (the bits are rare, but would be easy enough to just sell next to the plates if it became popular)

I don't know what monster decided that but it makes all electrical outlet work 5x more frustrating!

Cheap, easy to clean, only gets opened like once every ten years, cheap and takes paint well.

Also cheap
