I wonder if this varies with region / part of the country, or more just with neighborhood, and what size lawns they're mowing. A stander seems like it'd be great for mowing smaller lawns, but much less fun when every house in the neighborhood has 6 acre lawns in hilly terrain.
So, what's "around here" mean to you?
Most of my neighbors are mowing 4 - 6 acres, and every last one of these are mowed with 60" zero turns, either homeowner or hired. There are two neighbors with smaller lots (2-3 ac.?), and they both have 52" lawn tractors. Up the road a bit further, I see several houses mowed with standers or 48" walk-behinds, but they're on a flat plateau and mostly wooded lots with less lawn and more trees.
The only advantage I can imagine for a stander on a larger open property is less likelihood of getting drowsy when mowing all day. As fast and bumpy as a 60" commercial zero turn can be, you can get drowsy after several straight hours of making stripes... almost like counting sheep.
