I would never use a Phillips screw in anything that needs to be maintained over time. They're just far too easy to strip, and they're easier still if you get the wrong size driver. For example, a PH3 driver in a PH2 screw or vice versa are a disaster waiting to happen. Pozidriv screws are marginally better in this regard. You can use a Phillips driver in a Pozidriv screw, but to get the best benefit you will need a matching Pozidriv driver instead. The possibility of user error due to driver size mismatch remains. Note that the opposite is not true; using a Pozidriv driver to drive a Phillips screw will do even more damage than a Phillips driver ever could when the screw bottoms out, on top of damaging the driver itself. Torx screws are far better, and unlike Phillips and Pozidriv, the wrong size Torx bit will simply either completely not fit, or wiggle and spin fairly freely. If it does spin due to being undersized, the only damage you're risking is usually to the driver, leaving the screw still usable and removable. Note that the usual caveats about torque apply. If you're using an impact driver that kicks out over 200 Nm on its highest setting, you'd better be using a driver and a screw rated for that, regardless of what you end up using. Or you will snap something either way.
