Which is better for a homeowner starting out?

The 2-Tool Kit. It costs $149 at The Home Depot as of November 4, 2026 and covers drilling and driving, which is most home work. Add a saw later only if you need one.

Which has more power?

The 2-Tool Kit's brushless impact driver spins up to 3,200 RPM, well above the 4-Tool Kit's 1,500 RPM. The 4-Tool Kit's advantage is the extra tools, not raw speed.

Do the batteries last longer on one kit?

The 4-Tool Kit ships with 2.0Ah packs and the 2-Tool Kit with 1.3Ah packs, so the 4-Tool Kit runs longer per charge. Both use the same 20V MAX system, so packs are interchangeable.

Is the 4-Tool Kit worth the extra money?

Only if you need the circular saw and work light. At $350 at eBay versus $149 at The Home Depot as of November 4, 2026, the 2-Tool Kit is the better value for drilling and driving alone.

Which is easier to carry around?

The 2-Tool Kit, at about 8.28 lbs packaged versus 21.75 lbs for the 4-Tool Kit. The 4-Tool Kit's weight comes from the saw and the larger batteries.

Which has better user feedback?

The 2-Tool Kit has far more ratings, 4.7 of 5 from 5,185, against 4.8 of 5 from 26 for the 4-Tool Kit. The 4-Tool Kit scores slightly higher but on a much smaller sample.
