Rod, I think we're all "lured" by something or other when considering new purchases. Luckily, after using the 6D for a few days, I do feel like I made the right choice, and I don't feel like I'm missing anything (for my intended usage). Hopefully, you can at least make good use of the burst rate, etc. features you do appreciate on the 7dii. My main concern was the focal length differences, and I've decided I LOVE my current lenses on the 6D!
Luxx, low light capability was one of my main reasons for upgrading, so I think that contributes highly to my enjoyment of the 6D. I have previously purchased an EOS M for a "take anywhere/everywhere" camera and the ability to take video clips, but I've had it for months and taken only 1 or 2 video clips, so video did not come into my decision for a new DSLR. I've taught someone with a 70D the basics of photography though, and I was very impressed by her camera. Since you have both, it seems like a great combo!
So far, I've been too busy trying out different settings and situations with the 6D to pull the card out and look at photos on the computer yet, so does anyone know if Lightroom 4 recognizes 6D files? (LR4 does not recognize my EOS M files, so I have to convert all photos to DNG first and I find that annoying.)
