I am not a hater on them, just that I have had 5-6 now at this point that have failed to hold zero, lost focus, or just haven't dialed correctly over the years. 1 6x42 Fixed and the rest were variables of one kind or another. As a whole the 6x36's and older M8 4X's have been very good at maintaining a zero. I wished they made more stuff I liked as being a retired Vet gives me a great discount on them, but it's rarely used for scopes these days.
This has been my rough experience too. The 2-7s of a few flavors and the common 3-9x40 VXIIs seemed to be the biggest issue for me, but it wasn't limited to just them. They caused me to miss a few critters over the years and wound a few more which turned into rodeos. Most times it turned out I was a foot or so off at 100 yards. The 6X42s have been solid for me and my one 6X32 hasn`t shifted POI at all, though it is on a puny .17 Rem that gets thrown around a lot.
