Although Apple have been known to change things for change-sake, I find it is possible to take a Mac running Mac OS 10.2 and 10.12 and you will find your way around with ease. Of course, under the hood they've rewritten everything like DNS and actually using the hosts file etc. but from a usability perspective you are right that you end up fighting with the OS less (so I have found).
