well if price is not a concern your best bet would be a nightforce 1-4X24 NXS, but they retail bor about $1000think about how far you usually shoot, and if the deer is running or stationary. i put an aimpoint red dot on my slug gun because 1, i dont need magnification as all my shots are normally under 100 yards, and 2, red dot sights (and Eotechs)are the FASTEST sights period. which is greatfor jumping deer that are on a run (i walk and do drives mid day). 3, you can aim with both eyes open. the battery life on most aimpoints is 50,000hours, so you can pretty much leave it onfor 4 years
