RE: Red dot VS. Scope
Normally for less magnification at the same price point you get a better scope. Not to mention the less the power the better the eye relief, field of view and the brighter it will be. Also as a norm a 1.5-4 or a 2-7 will be more compact and lighter. You simply don't need 9X to hunt deer at most normal ranges.
And a 1.5 power is easier to get on a deer than a three power, and easier yet if you forget and leave your scope set at 9X which is pretty much useless inside of 100 yards.
It really is a personal preference though.
