There are as many people who prefer more compact A7x bodies as there are people who prefer bigger Canon bodies.A lot more advanced does not mean anything if for example one does not like the look or feel of the Sony or it does not have the lens you would like to use.No, Sony A7ii is $300 less and a lot more advanced.If you want the cheapest FF camera, also get a Canon.
besides, not everyone will agree with you that it is "a lot more advanced" .
Sony FE has way more lenses than Canon RF. What lens is the system missing?
