Square head screwdriver on Phillips screws?
I recently watched a vidio where the mechanic stated that square head screwdrivers (Robertson) work better on Phillips screws than a Phillips screwdriver.
has anyone ever tried this?

You'll also find what many people think they are using is a Reed & Prince screwdriver and not a true Phillips. They are in many screwdriver sets you get. Wrong one will strip easier.
Frearson vs Phillips
The Frearson screw drive, also known as the Reed and Prince screw drive, and specified as ANSI Type II Cross Recess, is similar to a Phillips but the Frearson has a sharp tip and larger angle in the V shape.[20] One advantage over the Phillips drive is that one driver or bit fits all screw sizes. It is often found in marine hardware and requires a Frearson screwdriver or bit to work properly. The tool recess is a perfect, sharp cross, allowing for higher applied torque, unlike the rounded, tapered Phillips head, which can cam out at high torque. It was developed by an English inventor named Frearson in the 19th century and produced from the late 1930s to the mid-1970s. The Reed & Prince Mfg. Company of Worcester, Massachusetts, was put into bankruptcy in 1987 and liquidated in 1990. Another entity called Reed & Prince Manufacturing Corporation, now of Leominster, Massachusetts, purchased some of the assets including the name at the liquidation sale.[30]As of 2022, both Frearson screws and Frearson bits are readily available in several sizes. The available screws are made of silicon bronze.[31]

Yes, I have found that to be true. BUT, you have to find the right combination. Not all Phillips head screws are designed to be able to use a square screwdriver.
How do I know this? I volunteer at the local State Wildlife Park. I'm a "handyman". Every screw type imaginable has been used there. Phillips head screws "strip" easily, and square drivers will often save me disassembling things.

Square head drive will work on phillips heads if the screw is sized for it. I love square heads. The rage now is all torx, all the time, at least on my building projects. I hate torx. The drivers strip too quickly.

Yes, they do. I was curious, so................. I let Google be my friend.
Apparently, there are 5 different sizes of Square Drive or Robertson screw drivers.
