I don't really have a dog in this fight but I did have an a7rii that the rainforests and deserts of Madagascar turned into a paperweight in 4 days. That wasn't such a problem as I had backup gear but the worst part was dealing with Sony for repair. That is what really set Canon and Nikon apart for me. I just can't see anyone serious about photography or having to rely on gear putting up with the kind of service I got from Sony which amounted to a total brush off and a big loss for me. I can't say whether things have changed since but my point isn't about which is better or worse in absolute terms. At the end of the day the choices and circumstances that determine how satisfied an individual consumer may or may not be with a product are as individual as themselves. Beyond that you're debating in a vacuum. Who really cares what anyone else does when you're looking for a product that suits your individual needs. Just because NASA takes a certain camera into space it doesn't mean it is suitable for everyone.
Sony Pro Support is top notch if you go through them....free overnight shipping both ways, fast turn-around, and overnighted loaners via lens rentals if you need it. Non Pro Support service historically has not been the greatest.
