I've owned a 7D since shortly after it debuted and I love it, performance-wise. Past iso 1000, results are iffy, and depending on the content I may find myself doing lots of pp to realize a decent print. I've owned a 6D for around two months now and I am thrilled with iq, dr, and high iso shots compared to 7D. I still love my 7D; they are different tools for different purposes. In good light the 7D is fine for whatever, but when the light's not great the 6D shines. Additionally, the 6D has superior dr that is always evident. DoF is easier with the 6D due to the ff sensor. AF, fps, are certainly better with 7D. With this combination it will take something monumental, I think, for me to move to 7D II whenever it comes.
