For general home projects, I may not need the highest torque rating, but I still want enough power to handle difficult jobs without struggling.
Comfort and Handling
I always check the grip, balance, and overall feel of the tool in my hand. A good rubberized handle and balanced design make a big difference when I am using it for a long time. I also prefer a compact body because it helps me reach tight spaces more easily.
Durability and Build Quality
