A tip it took me too long to learn: using an impact driver will make it easier to avoid stripping Phillips screws than using a drill/driver. The way the impact driver delivers impulses at high torque just makes it easier to keep the bit properly engaged, since it kind of "resets" between each impact. The effect was so dramatic to me that the frustration saved was more than worth the cost of a mid-range cordless impact driver.

But a lot of carpenters do prefer square or torx drive just to avoid the whole problem.
