Zorin has a commercial license for additional GUI front ends, installation support, and a bunch of "professional" apps. It's not clear if they've done something to make adobe/Autodesk/pro audio stuff work on Linux, pre-bundled their FOSS alternatives, or have made software themselves.
Personally, if I was looking for something "professional", I'd go PopOS!. But if I were a small or mid-sized business I'd consider Zorin Pro if I could get license to include additional support outside the installer... Or just buy System76 computers with PopOS! pre-installed and support built-in to their sales pipeline already.
That said, Mint is also very Windows (classic)-like in their GUI experince (intentionally). It also has one of the largest Linux communities focusing on GUI usability.
Depends on your use case on which flavor you should go. But for $50, I'm curious what Zorin's software suite is and might dive in.
