Hi Alan. Welcome to FM! Sometimes it takes a bit of time to introduce the newest gear to the review section. Until that happens, there's no way to leave a review for a given piece of gear. If you do a search in this gear forum for the two cameras (separately), there are plenty of opinions, discussions, and photos to look through as you make your decision. Best of luck!
Alan, perhaps given some time, as experience grows, features better understood and exploited, folks will write-up their findings. At least with the 6D, it's only been in hands for a short while.
