Do yourself a favor and compare themat a dealer if you can. I bought a major brand crossbow rifle-type scope for testing and when the illuminationwas switched on the internal reflections were so bad I could not see through the thing. Totally useless IMO. I gave it to a friend that obviously has much lower expectations than I do :-) For my old eyes a good quality reflex red dot can't be topped. I don't need magnification to shoot a deer at 30 yards................or 50 yards for that matter. I also shoot reflex sights on my 3D crossbow, sighted in for 30/40/50 yards.
