I meant as far as using that #60 in lowlight. It is pretty impressive . So your experience is that the S&B illumination is better than the Z6I? I have not looked thru the Z6I .

No, never looked through a Zeiss #60 in lowlight or any other lighting. My older Diavari is not illuminated and has a duplex style reticle.
For me, The Swaro Z6 illumination did not provide any benefits I felt were having the extra weight in the scope. I bought another just like it without illumination and am much happier with it. I don't have a lot of different scope experience, but for my eyes the S&B illumination is perfect.
