Our verdict
Both are self-propelled 21-in mowers, so the split is about power source. On specs, the EGO 56V wins on convenience: push-button start, no fuel or oil, quiet operation, and a rated 60-min runtime that covers medium yards. The Honda gas model wins on endurance and headroom, refueling instantly for large or hilly lawns where a single battery would run out. Choose battery if your yard is under about half an acre and you value low maintenance; choose gas for big lots, dense grass, or all-day mowing. Runtime figures are manufacturer ratings and fall in tall or wet grass.
