Privacy and best practices are nearly universal across most user-obsessive distributions like Mint or Zorin and by extension most if not all distributions. Don’t let anyone tell you that one distribution is more “private” than another.
Mint is simply just better than Zorin in everything that Zorin tries to do, perhaps if this was a year ago things would be different, but Zorin is just not as well maintained as Mint is.
If you like the look of Zorin, that’s okay, most people do. But all desktop environments can be customized to your liking.
You could just call the Free operating systems GNU/Linux or NonGNU/Linux.
“Vanilla linux” is vague terminology and distorts history.
