Just some comments about "need", as opposed to "nice to have":
In the Lower 48, most hunters--and that's mostly the deer hunters--rarely shoot beyond some 200 yards. As far as rifle accuracy and group size, anything that stays inside two MOA is gonna collect Bambi, and is usually plenty good enough for Ol' Wily Coyote.
So, IMO, repeatability of adjustments is nice, but not really necessary. At least for me, these last 40-some years, it has been a case of, "Set it and forget it," once I'm sighted in. I've never needed more than a 40mm objective lens, either. And type of adjustment hasn't seemed to matter, whether it's clicks or just a matter of watching the little marks on the adjustment knob.
I'm highly in favor of folks buying whatever they want, at whatever price-limit they set. I'm just saying that there is a big difference between what's needed to accurately hit where you want, and what's nice to have.
IOW, you can kill as many deer with a good used Weaver K4 on top as with Mr. Super's $1,000 whoopilah.
