In the battle between a screw and a bit there will always be a loser.
A hard bit that does not get chewed up easily will invariably chew up the screws if pushed to do so, or it will shatter. And a soft bit will wear down fast.
I have had pretty good success with a DeWalt brand bit over the last couple years. I get a double sided phillips (#1) and a double sided flat head, that way if one side busts I can just flip it over and not have to go find a new bit.
I think the key is getting good pressure between the two metals to prevent the bit from slipping out. If the bit (and drill) are strong enough you will probably be able to break off many screws given enough contact.
