Quick Verdict

The EGO POWER+ wins on overall performance and higher customer satisfaction (4.4/5 from 425 reviews vs. 4.1/5 from 1,527), but it costs over 50% more. The Greenworks 40V offers strong value for its price, especially if you have a smaller yard and want to save money. Choose Greenworks for budget-friendly, reliable mowing on a standard lot. Choose EGO if you prioritize longer runtime, more power, and a smoother self-propelled experience for larger or more demanding lawns.

Where Greenworks Wins

  • Price: At $399.99, it’s $209 less than the EGO, making it a strong choice for budget-conscious buyers.
  • Proven Popularity: With 1,527 reviews, it has a much larger sample of real-world feedback, giving a reliable sense of long-term performance.
  • Adequate Power for Most Lawns: The 40V system with a brushless motor handles typical residential yards up to 1/3 acre without issue.
  • Lighter Weight: Generally easier to maneuver, especially if you’re not used to heavier self-propelled mowers.

Where EGO Wins

  • Higher Power & Runtime: The 56V battery system delivers more torque and longer run times, ideal for thicker grass or larger lawns (up to 1/2 acre).
  • Better Customer Satisfaction: A 4.4/5 rating indicates fewer issues and higher owner satisfaction, even with fewer total reviews.
  • Select Cut Technology: EGO’s “Select Cu” (likely Select Cut) allows you to switch between bagging, mulching, and side discharge without tools, adding convenience.
  • Build Quality & Features: Typically includes a more robust self-propelled system with variable speed control and better overall construction, justifying the premium price.

Which Should You Buy

Buy the Greenworks 40V if:

  • Your lawn is 1/3 acre or less.
  • You want to spend under $400.
  • You prefer a mower with a high volume of positive reviews and proven reliability.
  • You don’t need the extra power of a 56V system.

Buy the EGO POWER+ if:

  • Your yard is between 1/3 and 1/2 acre, or has thick, damp grass.
  • You’re willing to invest more for longer runtime and stronger performance.
  • You value a higher customer rating and premium features like Select Cut and variable-speed self-propulsion.
  • You plan to expand into the EGO 56V ecosystem for other tools.

In short: Greenworks wins on value; EGO wins on performance and satisfaction. Choose based on your yard size and budget.
