Zorin vs Mint comes down to; do you like the color green or blue? Jokes aside they are basically the same. I prefer gnome(zorin) over cinnamon(mint). I also find Zorin does a better job guiding newbs from windows. For example if you would download and run a windows exe, then Zorin will show a pop-up telling the user about alternative Linux apps, or it will handle running windows apps for you through wine.

As a linux newb your choice of distro really doesn't matter too much. Just don't go for difficult stuff like Nix, Gentoo. Desktop Environment is where it's really at for newbs. So try out Kde Plasma, Gnome, Cinnamon and pick the one that you fancy.
