Rifle Scopes : Zeiss Line vs Swaro Line

I am from Alabama and new to the forum, but own both Swarovski Z3 4-12x50 and Zeiss Duralyte 3-12x50. To put this in simple terms, the Swarovski is a great scope but the Zeiss is brighter and more versatile adjusting magnification with the 30mm tube. for the money I personally believe the Zeiss is better. I do not have a Z5 or Z6, but the Zeiss is hands down better in low light. Everyone's eyes are different and I would advise looking through both at dusk or dawn. I will say for a fact there is not a $400 difference.
