I choose to shoot with Nikon gear. I find them to be a bit more friendly to the pocket. The customer service seems to be more hospitable too. As far as which is better? Well its all in the hands of the photographer. You can take the same shot with a Nikon and Canon and it would show no difference. I wont switch because you get vested in what you have as far as
lenses. The lens or glass is what will make your photography shine. I probably have a dozen Nikon lenses and if I were to switch well it would break the bank. Going into full frame from crop sensor (D7200) but this again is more money for lenses although not as much as it would be to jump ship to Sony or Canon.
