In my brief but storied existence upon this Earth, I have learned a few things about buying optics.
1. When you are contemplating optics of any description, bring your wife with you. She is probably less biased to brand names than you are and she probably has better eyes than you anyway.
2. Select three of the top contenders you have been thinking about.
3. Get the store attendant to accompany you and your unbiased wife outside with a couple of chairs. You will NOT be using your glass inside and under florescent or digital lights.
4. Focus the objective and ocular lenses to your eye (sharp reticle and target image) and then look at a street sign at least 100 yards away. See how clearly defined the edges of the letters/numbers are and compare all three scopes. Make notes about color rendition and clarity. Make sure you are sitting in a chair or are resting the optic upon a pillar or post for stability.
5. Adjust the scopes to your unbiased wife's eyes and let her go through the same process. Listen to her input and then compare again.
As an aside, grey, overcast, rainy days are the best for testing. The chances of your hunting/shooting on a perfect clear-blue day is remote.
If the sales associate is unwilling to allow this sort of testing when you are about to plunk down a large pile of shekels for the glass, say "Thanks" and walk away. They really don't have your best interests at heart.
Please note: The most expensive glass/most recognized name brand in the cabinet may not be the best deal.
I have a surprising number of Bushnell products in my safe. It wasn't planned that way, that's just how it worked out.
