Interesting, of course it is both a matter of taste, but - as always - also of sample quality.
I have dismissed the SLC8x42 when I tested it in 2015 as not being up to the quality of other alpha bins. A good upper middle class bin but overpriced here in Germany. I only ordered one recently because the dealer claimed to have the previous model as a demo, but the latest model arrived.
The SLC I have now makes my Noctivid´s images look a bit oppressive, oversharp, dark and flat where the SLC´s imagery is friendly, deep, airy, transparent. SLC almost has an AK prism look. Quite an achievement. Nikon EDG is outclassed, too. Ease of view is by far the best in the SLC, as Nocti gives me black outs in very bright light and Nikon EDG always needs precise IPD.
Now that was all very unexpected, but I am not complaining.
