I tried all kinds of scopes and red dot combos. When I carry a gun, I just carry one with front bead. Easy, not affected by rain, or bumps, and if you can call a turkey, he will be in your lap anyway. Partly why I have switched to using a bow most of the time.
To fully answer your question. The best scope I used was the Nikon Monarch 1.5x5 with the turkey circle. Fast target and bright. Took it off to reduce weight and just did not feel it was necessary. If I had to go back with a red dot or scope, I would go back with the Nikon. I should also point out that many times I am taking a kid, or "backing" someone up. In those cases, the scope is in the way on a moving bird.
