Which is better for driving long screws?

The DCK277C2. It includes a compact impact driver, which delivers concussive blows that a drill alone cannot match. The 2-Tool Combo Kit does not name an impact driver.

Which has the better motor?

The DCK277C2. Its drill and impact driver are both brushless, which means less heat and longer runtime per charge. The 2-Tool Combo Kit does not state a brushless motor.

Is the DCK277C2 worth the extra money?

For regular use, yes. You get brushless tools, an impact driver, two batteries and a charger. If you only need occasional drilling, the 2-Tool Combo Kit at its $129.00 low is enough.

The DCK277C2 is the safer bet. Brushless motors have fewer wear parts, and the kit ships with two batteries, so each one cycles less. The 2-Tool Combo Kit gives no motor or battery details.

Which is better for a first tool kit?

The DCK277C2 if you plan to build furniture or drive deck screws. The 2-Tool Combo Kit if you want the lowest cost for light drilling and driving.
