>>3413320Basically I think the Z6 is a no brainer for existing Nikon users; the FTZ adapter works flawlessly with Nikon AF-S lenses and the controls are almost the same.
The AF is a little worse in low light vs D750 (hunts more but gets there in the end) however it makes up for it by having much better AF in good light (Face detect, AF points all over the screen, super quick) which is where I use my camera 99% of the time.
>>3413321Yeah the glass collection was definitely a deciding factor. I walked into the camera store on boxing day with my heart set on getting an X-T3, but after giving the Z6 a go, and contemplating the hassle of selling all my nikon glass I impulse bought the Z and I'm happy to say I don't regret it.
I think heaps of people get caught in the trap of comparing spec sheets and taking the opinion of youtube reviewers too highly, best to try out the camera in store and see what suits your own situation best. I tried another tourist's EOS R while I was in japan last month and thought it was surprisingly great to use despite the torrent of bad press online.
