Where Sun Joe Wins
Cutting width and efficiency. The 17-inch deck cuts 31% more grass per pass than the 13-inch Simpli-Magic. This means fewer passes and less mowing time, especially noticeable on medium-sized lawns.
More power. The 13-amp motor delivers noticeably more torque through thick grass and light weeds. The Simpli-Magic’s 1300W motor (roughly 10.8 amps) can struggle in dense growth or slightly damp conditions.
Mulching capability. The Sun Joe is explicitly designed as a mower/mulcher with a dedicated mulching plug. The Simpli-Magic does not offer true mulching; it uses a side-discharge only, leaving clippings that may require raking.
Proven reliability. With 1,223 reviews and a 4.0 rating, the Sun Joe has a track record of consistent performance. The Simpli-Magic has only 69 reviews and a 3.4 rating, indicating a smaller, less satisfied user base.
Adjustable cutting height. The Sun Joe offers 5 height positions (1.5 to 4 inches). The Simpli-Magic has 3 positions (1.5 to 3 inches), offering less flexibility for different grass types and seasons.
Where Simpli-Magic Wins
Price. At $129.99, the Simpli-Magic is $100 cheaper. For a shopper on a tight budget who only needs to maintain a tiny, flat lawn, this lower upfront cost is the main advantage.
Lighter weight. The Simpli-Magic is lighter, which can make it easier to carry up stairs or maneuver in tight garden beds. However, the Sun Joe is still manageable at roughly 30 pounds.
Simple operation. With fewer settings and no mulching option, the Simpli-Magic is straightforward. Some users may prefer this minimalism, though it comes at the cost of versatility.
Which Should You Buy
Buy the Sun Joe MJ403E if: You have a lawn of any size above 1,000 square feet. The wider cut, stronger motor, and mulching capability make lawn care faster and cleaner. The higher rating and larger review base also suggest better long-term reliability. The $100 extra is easily justified by the time saved and better results.
Buy the Simpli-Magic if: You absolutely cannot spend more than $130, and your lawn is very small (under 1,000 square feet), flat, and free of thick grass or weeds. It will cut grass, but expect more passes and less precise results. Be aware that the 3.4 rating and low review count indicate a higher risk of dissatisfaction or early failure.
For most homeowners, the Sun Joe MJ403E is the better investment. The Simpli-Magic is best reserved for extreme budget constraints or as a temporary solution for a tiny patch of grass.
