I shoot both and I am fine with either. If you have friends that shoot, it wont hurt to match them. Neither will make you hit or miss or misrange at all. As long as your reticle is the same as your turrets you will be fine.
I started out with Mil/MOA and still shoot some like that.
Then I went full tilt and was always MOA. Did fine.
Little over a year ago I bought a few mil/mil scopes and love them too.
I will go out on a limb though and tell you that if your gonna shoot all by yourself and it would just be a coin toss, I say mil. But sometimes I let the reticle decide.
NF has a MOA reticle in their new 2.5-10 that I like better than the MIL version. So, if reticles are equal to you, pick what your friends have, if still alone go mil. You will be fine either way. Good luck
