The main difference between the three drills is the battery system. The DeWalt D25900K uses DeWalt's 20V MAX XR battery system, while the Makita XFD07Z and Milwaukee M18 Fuel use their respective 18V battery systems. This means that the DeWalt drill will be slightly more powerful than the other two drills, but it will also have a shorter battery life.

These drills are slightly less powerful than the DeWalt drill, but they have a longer battery life and are compatible with a wider range of tools.
The Ryobi ONE+ HP is a less expensive option than the other drills on this list. It is a powerful drill that is perfect for basic tasks. However, it does not have as much power or as long of a battery life as the other drills on this list.
