I just got the kompakt ratcheting 27 version of this. The 4:1 gear ratio as well as the ratcheting function are great when you have relatively longer screws or when you just want to drive in the screw faster before torquing down. When torqueing down, I would not recommend engaging the gear systems on either driver because they can be prone to failing. I know the ads say that a 50Nm torque can be applied but I think that is more of a marketing strategy. So for that reason, I like mine because it has a long hex shank that you can use a 1/4” wrench around to apply any extra torque you need.
