ZorinOS is a decent stepping stone for those coming from windows. It was my first Linux daily driver when I made the switch. It got me comfortable enough with Linux to dive in and start learning before I started distro hopping. I ended up on Mint and now just recommend that, but Zorin got me over the hump to become a full time Linux user.

Might be fun to make a live USB and see how much it's changed in the last ten years. I've got a 4 day weekend coming up.... might have to try that.
