I do not look at either of your parameters. I look at the quality of the glass first.A 1" 40 mm Swaro. with no red dot will be far better than a 30mm tube 56mm OL in a Bushnell.
Personally I never saw a single bit of help with a lit reticle for deer hunting in the waning light. They actually seemed counter productive to me.
Think QUALITY, not SIZE, or GIMMICKS. Tom.
