It's not what you're missing optically.
Some of the responses you're seeing are from guys that shoot more on a single weekend (maybe even a single outing) than you likely do in a couple of years.
If you shoot like many do here, there likely would not have been an inquiry.
This.
Anyone is welcome to use what they wish. If shooting to see if you're on the pie plate once a year and hunting with a short walk to a stand to shoot a deer at 75-100 yards is all you need, you're probably not missing much.
Shooting 100 rounds...or even 30 rounds....a couple of days a week, dialing adjustments from 100 to 500 yards, and comparing results, differences start to become obvious. When checking zero over a 4 month hunting season, usually hunting 2 days a week, some hunts being a short walk and some being a long ATV ride followed by a long hike, and the zero isn't where it was the last time you shot...again....differences start to become obvious.
Edited to add - aside from reliability, there are optical and user characteristic differences in scopes. Some of the higher $ scopes aren't as view friendly as some of the plain jane low $ scopes.
