I hear ya!
I bought a stock of socket head cap screws for servos (Microfasteners) and havent' looked back since!
I save the phillips head ones for the little jobs here & there.
Which reminds me.. my stock is getting low!
What really really galls me, are that kits still come with slot head screws as standard!!
The only good use for a slot blade screw diver is to open paint cans!
Then again, we have 'Robertson' screws up here. Patented 'safety screws'!
