I settled on the 6dii because of the better focus system, faster frame rate, and Dual Pixel CMOS for video. I have young kids and they move fast.
I want to go FF for two reasons. My best glass by far is the 70-200. I'm not spending $2000 on another lens anytime soon, and a FF would give me more useable focal length with my 70-200. I am (was) unable to shoot with it on my 70d because it was too long far more than it not being long enough. And I could get a teleconverter for it, which would maximize useable focus length with my best lens.
Second reason is because there is no good standard zoom option for EF-S. I have no problem spending $800 on the 17-55 2.8, but it isn't dust sealed. I like to bring my camera to the beach, fishing, in the rain , etc. The Tamron was OK but I broke it twice (zoom ring). I want to be able to use my stuff without worrying about it.
The 24-70L or 24-105L is too long on a crop.
I think the 6d is too slow for kids. Is that valid? Should I save up a little more for a used 5diii? Or 6d for now (there are some really good deals) and save up for a 5div when they come down in price.
