You can spend $10 on a scope or $1000 on a scope. The best one is whatever was on the gun when you killed the animal.
And in saying that, ill never own a swaro because they are rediculous in price and I have killed deer with $30 tascos and $50 simmons and $100-$250 nikons and leupolds. Comparing scopes is like comparing cartridges IMO. They all do the same thing.
