Okay, I'll bite.... Where are you hunting with them? 8.5 collect a lot of light, but I prefer 10x. I compared the Brunton Epoch's (10x)to the big 3, and they are very comparable.....With that said, at +$1200 you have many, better options IMHO. I compared my Cabela's Euros ($800) to the big three and Brunton Epochs, and would rate them very comparable. I really couldn't tell the Euros from the Epoch's, except about $500.00 extra for the Brunton HALO card for the Epoch's...All depends on your vision. If you are looking through "perfect" bins with not so perfect eyes, you may not notice a difference. A person with perfect 20/20, no astigmatism, no color-blindness, may notice a difference between Swaro SLC's, and Cabela's Euros, but my eyes sure couldn't....If your eyes ARE good enough, go with the Swaro's for about the same price. (Again, IMHO).
