Also worth looking at UTM [1] which uses the apple virtualization framework, while also being a simple frontend to QEMU.
The only thing I'd like to have is some sort of background daemon, so my VM don't stop if I accidentally close the UTM window.
Parallels was a night and day difference in both stability and responsiveness of my desktop. And copy/paste Just Worked as well. Definitely worth the $100/year subscription in my opinion.
Having said that, yeah, Parallels performance still wins.
