All five models deliver [approximately] triple the 450 in./lb. torque of a typical 18v cordless drill/driver, with no counter-torque to your wrist. All models are ambidextrous; i.e., they work the same in either hand. All models feature a 1/4″ hex socket with a snap-chuck to securely hold drill or driver bits. Impact drivers can be quite noisy when “impacting” and all are reversible with variable speed triggers. The four multi-speed models use electronics versus a gear box, which is a good thing. (i.e., drills that change their speed range via a sliding switch connected to the gearbox can strip gears if said switch is moved while the tool is running.)

Depending on which factors are most important to you, your [specification & feature] rating won’t necessarily agree with this conclusion. For instance, having multiple speed/torque choices; 2 speeds are better than 1, and 3 speeds are better than 2, having a short tool so it would fit in tight quarters, being light-weight etc.

No model is the best in every area, be it warranty, charge time, tool length, or whatever. Price had little sway in these rankings, other than designating the Hitachi “best value” because of its lower cost.
