I like landscaping work, and maintaining a large lawn. But I also value my time. A lot. When I went through this decision I got a zero turn and couldn't be happier. Mine's actually a front mount Grasshopper, but any of them in a commercial duty series would be good. I spend very little time on maintenance, mostly proactive which keeps things ready to use and from wearing out too soon. I think I cut my mowing time in half compared to a rider. I mow around 6 acres, have slopes and hills, and hundred(s) of obstacles or trees. I love to go out to mow though, as I can get it down in a reasonable amount of time, and have a quick sense of satisfaction.
My wife comments when we pass large yards with some guy slumped over the wheel of a riding lawn tractor, creeping along. It looks like it takes all day. She loves how fast we get ours done.
edit to add: a commercial duty mower will have much higher blade speeds, and deeper/taller decks to handle more clippings. you can mow faster, and when wet if needed.
