A lot of it is also what camera fits your hands best, for some the smaller cameras are too small for their big hands. Do your fingers naturally fit over the buttons? Can you access the important functions without having to page through menus? I think it is more about function and form, being comfortable with the camera. Most cameras perform quite adequate unless you have a special need.

The camera doesn't do the most important part of photography and that is see the possibility of an image. You have to develop that skill, the more comfortable you are with your camera the easier that is to achieve.

Sorry no brand persuasion here.
