As a long time F class competitor, I lived in a world of SFP and MOA... converting to mils took less then 5 mins. For scaling groups, targets, most will continue to talk in MOA.... for adjusting for distance/drop, you figure out distance with your rangefinder and adjustment with your ballistics dope. Precious little math needed nowadays.
If you decide to move to a FFP scope (either MOA or mil), hopefully, the reticle and turret adjustments match. If yes, then you just use the reticle like a ruler and dial/hold off as needed. The biggest improvement I have seen over the last 10yrs is where the reticle AND adjustments actually match up... repeat... and are reliable... and often, don't cost a fortune.
For games where you are constantly adjusting for various target distances, I vote mils... so much easier to do base 10 math. If I am working with another shooter, so much easier to talk adjustments in base 10 math... not a fan of fractions under stress. Again, no math involved... see impact, scale adjustment, call out the number... done.
I would definitely worry more about the parallax adjustment range. That can be very helpful with rimfire at close range. There are plenty of scopes that offer adjustment down to 10m. Budget, features and brands I will leave to your tastes
I am very biased towards Athlon, Sightron and Delta.
