I picked up a refurbished Canon 7D Mark II today from the Canon store to replace my Rebel T3. I wanted something that could handle a higher burst rate while taking photos at drag races. The T3 was only capable of 3fps whereas the 7DII can do 10. Earlier this year, I was thinking about buying a Canon 6D because I thought I needed to eventually move to a full frame sensor camera. The 6D tops out at 4.5fps which isn't much faster than the T3. While both cameras have built-in GPS, I didn't need the WiFi that the 6D comes with. I also liked that the 7DII has a built-in flash, even though pop-up flash tends to make images look bad. I liked that if I needed a flash and didn't have a speedlight with me, I had the built-in flash as a backup. Another plus for the 7DII is that it has 63 AF points where the 6D only has 11. My T3 had 9 so 11 didn't seem like much of an improvement.
