No. It is the control approach.
I tried a Sony mirrorless. While it took great images and had better programming features I just couldn't work with the control approach and Sonyspeak in the menus and organization.
I now also have a Panasonic and although their control approach also differs from Nikon somehow I'm able to work with it.
Panasonic's ergonomic layout of controls and logical, clear menu organization is what got me, AFTER I discovered their GH series' video and audio capabilities.
I used Nikons and Canons for years. Canon menus are great, Nikon menus are so-so. I used both about equally from 2003 to 2012, and got really tired of having to think when I picked up a Nikon. I hate thinking about my tools instead of my task. Still, I liked VERY DIFFERENT things about the two big brands back then. I used each for a different purpose.
I really switched because I had a tremendous need and opportunity to mix stills and video in my work. The Panasonic cameras were best at it. I had no problem ditching my old glass and starting over, because not doing it was really not an option for me. I needed the features. I wanted to travel light, and "do it all" with one system.
If you stay with a brand because of the glass, and what you spent on it, I get it. No one likes to admit to himself that he has "sunk costs". You didn't make a mistake. You just changed directions. That's okay! It can work really well.
If you have nothing, and want to hedge your bets, buy Canon dSLRs and Canon L or EF-compatible lenses. They are adaptable to Sony, Panasonic, Fujifilm, and Olympus cameras with smart adapters that retain most of the automation. Nikon lenses can be adapted, but only with manual control.
If menus on your camera offend you, try Canon and Panasonic. They just make sense.
If you have lenses dating back to 1959, I understand. You're stuck with Nikon because they're so damned compatible. My old Nikon glass still works on modern bodies.
If you have most brands, they change mounts every 15-20 years. That can be advantageous, because fresh engineering can work better. Canon has changed lens mounts at least twice since I used an FX back in the late 1960s. I thought both changes made perfect sense.
Fortunately, there's a market for used lenses. And eBay is a wonderful place... So don't feel stuck. If you HAVE to have a new camera platform because it does things you need to do, and your old platform doesn't, JUST SWITCH. It's a pain in the posterior (and wallet), but can be worth it.
Brand loyalty can make sense, or be irrational. It all depends on your circumstances.
