I don't see it suggested here, but the 1.3x crop is a bonus vs. the 1Dx or 5DIII(for sports/wildlife).
Totally agree I tried ff with a 1Dsii but missed the crop reach of my 7D so sold it within a month. When A good mk4 came up for sale I thought give it a try and I love it. IQ is stunning, the extra frames per second are noticeable over the 7D when needed, the battery life is crazy, it feels great in the hand, but most of all the x 1.3 crop is perfect even with my max 300mm reach lens for sport and wildlife.
My 7D is now my wide angle kit 8mm Samyang and 10-22mm Canon
1Dmk4 24-105 and 95% 70-300L
No regrets for not selling my 7D as well and getting the 5Diii, a 2 body set up comes in very useful.
