I am fortunate enough to own both of these fine cameras and will share my thoughts on them. First of all I do not regret the purchase of either and would recommend both to prospective buyers. In all fairness I should point out that I have a more extensive lens collection for the Nikon. I like the Nikon because it has two SD card slots. I know many who feel that not important but I have been victimized before so it means a little more to me since then. I also think the flash and flash commander in the Nikon is better and cheaper. I have an SB700 speedlight and use it as a slave with nothing more to buy. The Canon has no built in flash so I have to buy two speedlights and a trigger. The Canon viewfinder is smaller and I find myself creeping closer to my subjects to get the composition I want. I like the Canon built in GPS feature, it saves a step in post P. I also think the Canon light meter is more accurate than the Nikon. I use exposure compensation on the Nikon a lot. The Canon not so much. I don't use either to the extremes that ISO ranges are that important to me and I use neither to shoot video. Like all the cameras I've owned since 1968 I've yet to buy one I didn't like, and these two are no exceptions. As far as images are concerned it would be hard to tell them apart. A professional may be able to squeeze out advantages in either one to his/her benefit, but I think the photos are equal. I think they are both great products and for Nikon guys, buy a 750, for Canon guys the 6D II is a great camera.
