Reddots work like crap on small game beyond short range IMO. Tried one a hunting gun and while great for fast moving coon it sucked for squirrel hunting. Other than that "best" is gonna be defined by your budget. I like 2-7x scopes in the $150 range on my rimfires and avoid AO like it's the plague. My main hunting .22 wears a 2-7x Redfield.
