Major differences between Navigator model years 2018-Present?

[Toonstop]

Hi there!

I'm curious as to what the meaningful differences are with each model year from 2018-Present of the current generation navigator.

Specifically I would love to know about:

Interior feature differences?
Software differences?
Engine/drivetrain differences?
Common failure points to each model year?
Overall best model year?
Overall worst model year?

Thanks!
