Purchased the 24-70ii in 2014 and think it's a terrific lens. Great focal length for me, and great IQ. I use it on a 6D body. That being said, I just don't use it much at all. I shot 1 wedding with it, and since then stopped doing paid gigs. For personal use, I take smaller cameras now, like my Fuji. So really it's not the lens itself so much as I just don't use the DSLR that often for personal shooting anymore.
At the same time, I don't want to completely rid myself of DSLR as I still think there are areas it performs better than mirrorless. But I think shrinking/lightening my kit even more may get me to take it out more. So I was considering selling the 24-70 and replacing it with 2 small lenses, maybe something like the 35mm IS and the 85mm 1.8. 6D with the 35mm IS would be a small and fairly light kit and I like the 35mm focal length.
