At the 3K+ price, it's all about what reticle and features you like. Unless you got a scope with bad glass, I think just about everyone agrees you get diminishing returns on investment once you hit that $3400 price range.
I have the 2020 built PMII 5-25 with the Grid reticle, and I love it. The clicks are smooth and positive, sometimes too positive. I skip over the first .1 mil adjustment due to the MTC feature, it tracks well, the glass is super clear even on overcast days. The eye box is very tight it seems.
My buddy has a ZCO 5-27 MPTC 3 reticle. Glass is wonderful, but I've looked out to 1000 yards between his glass and mine. I can't tell the difference with my eyes. I'm sure there's some type of test to show how much better it is, but with my astigmatism I can't tell the difference. The clicks are a hair less heavy compared to the PMII, but supposedly they have some type of different style of erector that doesn't wear out over time? They're so new, only time will tell if that's marketing hype or it lives up to the claim, but I'm willing to believe them. The turrets are WAY more low profile than my double turn locking turrets. It sucks to buy another SPUHR mount for a 36mm tube, when everyone else uses 34mm.
I like both with the exception of the weird circles on the ZCO, but I'm used to my Schmidt reticle so I can't knock it.
In my neck of the woods my scope runs almost the same exact price as a ZCO, I say get the ZCO if you're shooting PRS/NRL competitions. If you're shooting extreme range, the nicer glass with non blind eyes might be really worth it for ELR matches. Shooting out to only 1000 yards, I say it's a wash to my eyes.
I'm still going to buy a ZCO regardless because F the Poors.
