From another comment in this thread, Zorin is basically Ubuntu with a theme for the desktop environment. And the pro sells you a bunch of free software. May I recommend something like Fedora instead? It’s also easy to use (or is supposed to be - I only use it on my laptop for school), and is more widely known and accepted by the open source community from what I can tell. Every time I hear about Zorin it’s bad (or at most neutral) haha
