I haven't used Zorin. From what I've read about it it's issue right now is that it's not updated very often. I think it's main appeal is that it has similar vibes to Windows, which makes it attractive for people who want to try Linux for the first time, I guess.
The distribution I used when moving to Linux was Mint, which is also a smooth transition from Windows due to its desktop environment. Also based on Ubuntu, but is updated more often. It also works flawlessly (at least in my time with it).
Right now I'm using Pop OS, and I'm quite happy with it, although I am experiencing some freezes since a couple of updates ago...
