In my work I've used Slot, Phillips, Torx, Roberson, Hex or Allen, Posidrive and others.
For screws, wood, and sheet metal the Robertson is about the best that is readily available.
A well made Rob. screw can be given a light tap onto a well made Robertson screwdriver and it will stick, usually quite tightly.
Biggest problem I seen now is too many mfgrs. making scrap everything so even a good Robertson won't fit/stick reliably anymore. Worst are the so called multi purpose combination heads, slot, phillips, robertson lousily made so NONE them work well.
One thing to watch out for in a lot of ELECTRICAL equipment is the screw heads are POSIDRIVE , NOT Phillips. Interchange them and you will very likely ruin the screw and then have trouble loosening or tightening. They look very much alike but are NOT. The Pozidrive is a good design and can usually be i.d. by looking at the screw head. Between the 4 drive taper slots will be 4 lines radiating out. If you are working on electrical equipment and the screw head looks like a Phillips, BEWARE, it may not be and trying a phillips in place of may ruin the screw drive.
In the link the Pozidrive is the second from the left.
Another useless tidbit maybe but in particular I saw lots of the ruined "Phillips" that were in reality the POZIDRIVE and it caused a lot of grief. To the point I would buy the other guys a set. Was cheaper than the fighting with monkeyed equipment..
