A drywall screwdriver is specifically designed for fixing the plasterboard,
it has a depth stop & a clutch which countersinks the screws to a constant &
predetermined depth.

Like he says.

I have mixed experience with them. In ideal conditions, they're fast.
The moment you have to work in awkward corners, the slightest bit off-
centre or take a funny grip, they tend not to drive screws cleanly
home.

For all those spots, I find a compact Li-ion cordless with a good
torque clutch, though slower to drive, gets it right more of the time
- so is better overall.
