I too am with Redsey on the "spinny" screwdrivers. I have #2p and straight blade in my pouch at ALL times. The #2p is for everything up to #6x1.25" drywall screws.
For regular drivers I am another fan of the German made Wera, Wiha, Witte brands. They last much longer than others and are made VERY well.
I also use a Makita impact driver to install devices (in quantity). It's not worth carrying it for 2-3 devices.
Once you get the right feel it is perfect! Those cordless screwdrivers are WAY to slow.
