Ryobi 18V ONE+ 6-Tool Combo Kit vs Ryobi ONE+ 10-Tool Combo Kit

Both kits run on the same ONE+ battery platform, so the real choice is tool count versus weight and simplicity. The 10-tool kit adds an angle grinder, jig saw, sander, nail gun and a third battery, which covers more jobs without buying anything extra. The 6-tool kit is lighter, easier to carry and store, and covers drilling, driving and cutting for most DIY work. Owners of both praise the battery sharing and the 3-year warranty; the common complaint is the brushed motors, which are louder and less efficient than brushless.

• Choose the 6-tool kit if you want the core drilling, driving and cutting tools in one lighter bag and don't need a grinder, jig saw, sander or nail gun.
• Choose the 10-tool kit if you want the widest tool coverage up front, including a grinder, jig saw, sander and nail gun, plus a third battery.
