Yeah flat heads are terrible. They are always the reason if I get injured by my screwdriver.
Firstly, theres no geometry preventing the bit from slipping out. Secondly, greatly exacerbating the first, you need to press hard to prevent the bit from camming out, which increases the risk of it slipping out.
Both problems combined causes the bit to slip out with very high force. If you happen to be holding the workpiece, you can injure yourself real bad.
Is the screw going to slip out while I’m screwing it in or out.
Do I have a screwdriver or screwdriver tip for that screw when I need it.
Criterion 1 eliminates the flat head and Philips points. They’re terrible because they slip out. The flat head not only slips out, it slips out in the most dangerous ways.
But, criterion 2 eliminates most of the other designs. Even if you’re Canadian, which means you do have a Robertson screw driver, you might not have the right Robertson bit. Unlike with Philips or slot, the size of the bit really matters.
Ikea does a great job of handling this situation because they mostly use hex screws and bolts (which are great), but they also supply the required driver with the parts (which is necessary because many people don’t have a tool to tighten hex bolts).
Both Phillips and slot screws are fucking awful.

I fucking hate flatheads.
Flat heads exist because they were the only thing we could make for a long time.
Philips was made to strip heads.
Hexagon the the true master head. No camming out and If it starts to strip, you can smack it with hammer to return it to a working shape.
IMO the only two criteria that matter are:
