The WORX wins for users who prioritize convenience, quieter operation, and variable speed control on smaller, flatter properties. Neither is universally superior—your terrain and willingness to manage gas or batteries decide the winner.

Where PowerSmart Wins
Lower upfront cost. At $80 less, the PowerSmart is budget-friendly for those who don’t mind gas engine maintenance.
More cutting power. The 170cc OHV engine delivers consistent torque through thick, wet, or tall grass where electric motors can struggle or drain batteries quickly.
Wider cut. The 22-inch deck covers more ground per pass, reducing mowing time on larger lawns.
Better for uneven or heavy terrain. Gas engines maintain power on slopes and in dense growth without the range anxiety of battery packs. The self-propelled drive helps on inclines.
No charging downtime. With gas, you refill and keep going—ideal for yards over ½ acre where battery runtime may require a second charge.
Where WORX Wins
Quieter, cleaner operation. No gas fumes, no loud engine noise, and no need for oil changes or spark plug replacements. Works well in noise-sensitive neighborhoods.
Variable speed control. The WORX lets you adjust ground speed independently of blade speed, giving finer control around obstacles and on uneven ground. The PowerSmart has a fixed self-propelled speed.
Lighter and easier to maneuver. Cordless electric mowers are typically lighter than gas models, making them easier to push manually and store.
No fuel or maintenance hassle. Skip buying gas, mixing oil, and winterizing. The WORX is ready to go with a charged battery.
Better user ratings. A 4.4/5 average suggests slightly higher owner satisfaction, likely due to convenience and ease of use.
Which Should You Buy
Choose the PowerSmart if your lawn is larger than ½ acre, has thick grass or slopes, and you don’t mind gas engine upkeep for a lower price. It’s the practical choice for durability and raw cutting force.
Choose the WORX if your yard is under ½ acre, flat, and close to neighbors. You’ll appreciate the quiet, fume-free mowing, variable speed, and minimal maintenance. The higher price pays for convenience and cleaner operation.
If you’re undecided, consider your tolerance for maintenance. The PowerSmart will outlast a single battery’s charge but requires seasonal care. The WORX is simpler day-to-day but may need a second battery for larger lawns. For most homeowners with average-sized lots, the WORX’s ease of use justifies the extra cost.
