I have no issues with Zorin charging for the pro edition of their OS, FOSS software can still be paid software. I am currently happy with Mint 19 and have donated to the Mint team so in a way have paid for this OS. But might look at Zorin to see what its like for when support end on this current Mint version in a few years.
I did try WINE a few years ago as my partner needed to run Corel Draw for her work. But after much trying i couldn't get it to work in WINE so in the end I had to spin up a Windows 7 VM and run Corel inside there.
