I'd choose a scope suitable for the rifle's purpose and accuracy potential. I've killed several pickup loads of jackrabbits using a run-of-the-mill rimfire rifle with a cheap 3-9x on it, and I've shot ragged hole groups at 50 yards with my 52 repro wearing a VX-3 4.5-14x40 with AO. I think AO is well worth having on an accurate .22 rifle, at least for shooting paper.

Don't be the darkness.

America will perish while those who should be standing guard are satisfying their lusts.
