I've never been a knob twiddler. I like a scope with some hash marks or dots (preferably some for windage, too). The Nikon on my AR pictured above has circles which are kinda neat... I think personal preference is the biggest factor on what reticle works best for you.If you prefer not to twist knobs then the next important factor will probably be reticle style. BDC tuned to approximate ballistics or some version of mil-dot/mil-hash reticle?
