Is a self-propelled or push gas mower better for my yard?

Across the reviewers we read, the consensus is that push mowers like the AMERISUN 21 and PowerSmart 18 are lighter and cheaper and fine for small, flat lawns, while self-propelled models (SENIX, YARDMAX) reduce fatigue on larger or sloped yards. Community threads repeatedly note that single-speed self-propelled drives can feel 'too fast,' so variable-speed or CVT systems are favored for control.
