Pozidriv is very uncommon in the US.

Philips (00, 0, and 2) are by far the most common screw heads here for most people. (Pretty much every household will have these for changing batteries, assembling furniture, doing minor repairs...) Slotted screw heads used to be ubiquitous, and the screwdrivers still are, though mostly for use as pry bars. You'll see some socket-head hex-drive stuff, in a mix of metric and fractional inch drives (which can inform you on how US-centric the design and manufacture of the product was), and maybe some Torx (especially in electronics). I've only seen Robertson in drywall and decking screws at the hardware store, and I haven't yet seen them used in someone's home.
