I do want a Mil Dot reticle with 1/8 or 1/4 MOA adjustments Its what I learnd with so Im more comfortable with that set up . I guess It would not be a deal breaker if I had to learn a new way to do range estimation .
Mil/Mil is awesome if you like shooting a mildot, because having your adjustments match your reticle just makes exponentially more sense. It's especially nice for dialing up adjustments and calling your own shots because you don't have to do any math to make adjustments that you see through your reticle, you just watch what you see and adjust accordingly. I held off getting away from MOA adjustments for a long time, but after I made the switch I really wished I'd made it sooner.
