Best customer service (if you ever need it) goes to Leupold, hands down.
Brightness goes to the Bushnell. Bushnell also has the Rainguard coating if you plan on being out in wet weather.
Edge to edge sharpness and resolution go to the Nikon.
None of the above scopes are noticably better in any of the above categories except for the customer sevice. You will be happy with any of the 3 models. _________________ Best Regards,
