My experience (Salt Water) is if the Fillister Head screws are going to come out, they will come out with a hand impact driver (and heat if necessary). If they refuse to come out and you break them off, well they would have broken no matter what you were turning them with. So the driver style really isn’t the issue.
Now about that stainless steel: Again in my salt water experience, the aluminum around the stainless screw threads will corrode worse than it does with steel (more dis-similar). And when you do break them off, they are harder to drill out. Not only harder, but they work harden, making it even more difficult to drill.
So…if I happen to be the guy removing them 50 years from now, please just put steel screws in it, and Fillister is fine with me. Yeah, right. As if I’ll still be around 50 years from now!
