I've got 10X and 12X in the Milquad models.
They are both easy to like. The reticles are fine enough to both easily bisect a 1 MOA aim point.
For all around, I'd choose the 10X for the slightly better FOV and brightness.
For a dedicated paper puncher, the 12X might be a little nicer.
I put the 12X on a couple of heavier dedicated long range rigs, and the 10X on a more all-around type of mid-weight 308.
Pretty hard to go wrong with either.
