Are you referencing an actual tractor or a "riding lawn mower?" A cheaper zero turn residential unit our a more expensive light commercial/commercial unit?
My range is over 10 acres, with 7 of it in turf height grass (whole property is 30). It takes a LOT longer to mow with an actual tractor and considerably longer (probably double) with either lawn tractor.
In fact, my short game area/wedge range is a lil over 1 acre and I can mow it, in reasonably dry conditions, in 15 to 20 minutes....and that's piddling around adjusting heights, etc. A zero turn is WAY faster than a lawn tractor, to argue anything different is ridiculous. Why do you think PROFESSIONAL lawn services use zero turns virtually 100%?
"Versatility?" I can and do pull anything and everything with my zero turn that my 2 lawn tractors can pull (and then some....diesel is pretty powerful) We drag tubs full of range balls (several thousand balls) around in a cart that's attached to a zero turn.

Now, if by versatility you're referencing a commercial unit with box blades, etc etc etc. that are capable of grading a road, attaching a loader to, etc then you're 100% correct (you have to be). But, again, I have 2 Kubota "landscape" tractors (an L2900 and a 3830 both with buckets) that will get the job done much more efficiently and much quicker than any light duty commercial lawn tractor. Better PTO and much more hp, etc.
The problem with debating this type of subject is the subject matter has to be properly defined, etc. There's a BIG difference between a light duty residential gas mower and a commercial use mower....gas vs diesel....a small lawn tractor and an actual tractor, etc.
Btw, my farmer/rancher buddies laugh at what I call a "tractor""... either of em....hehehe
........ it's all a matter of "perspective".....
