I have an older Swarovski 3-18 on my 20 Vartarg. Ill have to put them side by side and let you know. The glass is very clear, true colors , and no chromatic aberration. My buddy loves Swarovski and thats pretty much all he hunts with. In the last few months he was purchased a few Tracts and is very pleased. They are too different animals and the Swarovski is hands down the top dog. No way would I say they are identical.
