Fair comparison, for which I can provide some real world info (in contrast to the usual annecdotes). The winner of the NSWRA Queens 2021 in the Sporter/Hunter class used a Zerotech scope on a factory Sako 6.5cm. He ran out of elevation at 800m, and had to use markings on his reticle to kentucky his elevation. He still won aggregate for 800m, on day 3, which I thought was pretty phenomenal. Meanwhile I ran the vortex strike eagle 5-25x56, and won silver for aggregate at 800m by a couple of decimals. Really not much in it - I was running a classic 155gr 308 SMK palma load.
The FFP reticle on my strike eagle is useful for PRS matches, or anytime you are quickly switching between distances. Otherwise when you have time to adjust, all that reticle stuff becomes pretty useless. Just dial in and shoot well - that's 99.9% of the battle. Simple, don't shoot when the wind is moving about
If you are extremely in tune with the wind (which takes much experience and a high degree of discipline come the days), you can use the horizontal subtensions to correct for possible wind switches. Sometimes I care enough to try and do this. But i'm mostly a TR shooter whereby I just consume might sighters, then wait when the wind is misbehaving. This F-class stuff sure is fun, but not my specialty.
Getting back to OP - aformentioned guy swore by his Zerotech claiming it had greater brightness and clarity, for the pricepoint. I'd be inclined to believe him. Meanwhile my strike eagle is O-K in terms of clarity, but it's not as bright as my older Leupolds, which are smaller obj go figure. Nevertheless the strike eagle is packed with features for the pricepoint - just is a tad milky/dull and quite heavy.
A FFP is helpful for measuring moa at any distance.
All said and done, as an owner of the Strike Eagle, and an admirer of Zerotech, I'd be leaning toward the ZEROTECH TRACE ADVANCED 4.5-27x50mm RMG MOA for roughly the same price.
Hope these point may help you a little.
