I always reach for the non-ratcheting screwdriver when working on electronics. I find the ratcheting mechanism on all drivers I've used to have too much resistance and just start screwing the screw back in rendering it useless and bulky. A bit drive with an end cap that rotates seems to work best for me.

For automotive it's a different story, but then I'd use a ratchet wrench anyway, and fixed screwdrivers in the engine bay as the bits like to fall off in the worst places.
