What does Zorin add as a distro other than pre-installed gnome extensions and apps?

Ok i know this might be a really hot take, and i am a beginner so i might be stupid (most likely).

However, things i firstly thought were features that were added by Zorin's developpers are apparently just some gnome extensions. Probably any other distro will be able to achieve the same UI with these extensions.

So, does Zorin actually add more features that i don't know about (that are native to Zorin) or are most of the sub-distros (the ones that are based on larger ones like any Ubuntu-based distro or Arch-based distro) just bunch of pre-utilized Linux with little to no additional features?
