Shooting at 12x-16x with FFP, either can work. Though the 1moa reticles tend to be reserved for the higher mag scopes.
FFP, reticle/turrets with mil/mil when shooting up to about 16x are OK. At 16x and up, I prefer my FFP scopes to be moa/moa.
For SFP, I kinda prefer mil/0.25" with a 10x mil reticle. And that is the most common type of SFP scope.
I know there are also 1/2mil reticles and 2moa reticles that work well at the higher and lower magnifications. I'm talking about 1mil-dot and 1moa reticles. For mil, I prefer standard mild-dots, though with more than the typical 5 subtensions. For moa, I prefer 1 moa subtensions spanning the entire FOV, preferably with additional divisions or numbers every 5 to 10moa.
Note: moa turrets are sometimes lumped in with 0.25" and 0.125" turrets. There is a subtle difference in their increments and their use.
