have the 4x12 Leupold on a couple of rimfires, and its a tad less critical of head position/eye relief for me.

Also have the 3x9 AO on a couple, and i do like the compact size. and i would lean that way if this is a hunting rifle...if shooting more paper, i might go the 4x12 AO...

and, just to make it MORE confusing, the Bushnell Elite or B&L Elites, both the 3000 or 3200 series, make great rimfire scopes, focus up close nicely, and are of similar mass to the Leupold 4x12.
