I have a 7D MKIII body sitting at the camera store with my name on it
A 7D MK 3?!!! WOW!
Looking at the images of others who have had the camera for a short period of time isn't a great way of making a decision IMO. They may not be your style, or they may not have perfected their techniques yet, if the store has a good return policy I would pick it up and see how you can do with it.
