Good review on 70d vs the 7100 except you seemed to have missed a few points about the 70D. For example it has an amazing auto focus in video mode probably one of the best on the market for dslr, also the Wifi feature that allow you to control the camera remotly with a smart phone, I use that feature often with my 6D.
By the way your training videos are some of the best anywhere.
