Phillips has been such a standard for so long in the United States I don’t think it’s going anywhere, and Pozidriv has made basically no inroads; in fact the only Posidriv screws I own are part of an E3D 3D printer extruder.
I encounter a LOT of Phillips heads, quite a lot of Torx, at least here in America a lot of carpentry screws are starting to standardize on T25 Torx drive. A lot of them include a T25 driver bit in the package, and they are SO much better than Phillips. Drywall screws are still commonly #2 Phillips. Pocket screws (washer headed wood screws) tend to be square drive for whatever reason. Machine screws are either Phillips or Allen. I find a lot of appliances held together with small external hex sheet metal screws, if not Phillips.
I bought a 50 piece bit kit and it came with no less than 8 #2 Phillips drivers.
