Have you used one? They are extremely ergonomic. More importantly, reliable and durable. Cheap cameras fail all the time.
As far as Canon/Nikon go, one is not better than the other overall. They are only better in certain use cases. For example, Nikon D500 or Nikon D5 are the ultimate pro sports photography bodies. The competition from Canon, the 7D Mark II is still insanely good, the D500 is just slightly better at sports because of higher frame rate, slightly better autofocus, etc.
Same goes the other way around. Canon is way better when it comes to video than Nikon across all bodies, although they have more recently relinquished the video crown to the likes of SONY, Panasonic and others. Nikon's video capabilities are way way way behind, though.
As for which one is more intuitive, it's what you are used to. The user interfaces of Canon and Nikon DSLRs are direct descendants of film cameras going back to the '70s or even older. For example, you know how Nikons all have that red stripe near the grip? That's because they are all based on the design of the Nikon F3 (one of the greatest SLR cameras of all time) which came out in 1980. Canon cameras say Av and Tv instead of A and S on the mode dials because that's how Canon has always done it. My Canon A-1 from 1978 was the first to have those modes, and it's written the same way.
Some people are used to one, and some people are used to the other.
And the same goes with lenses. They are just very subtly different in terms of the image they create. Which one is "better" is subjective.
