I went from a 7D to a 5D 3, and mostly do sport stuff. Very occasionally I miss the higher FPS of the 7D. What I miss most is the buffer depth to write raw + jpeg whilst using the highest FPS of the 5D 3. But the IQ of the 5D 3 surpasses the 7D by a significant margin - and at higher ISOs by a very significant margin. I'd go back to a 7D in heartbeat if it married the FPS of the 7D - or slightly higher with the IQ of the 5D 3, and as a bonus, the AF of the 1DX. Not bothered about a gripped body, not bothered about articulated screens. Not bothered about dual card slots either to be honest - not unless it's dual CF.
