For Linux yes I started using KVM and it works just fine for my needs on a workstation.
For Windows hosted VMs I preferred VMWare Workstation. It has a workflow that worked for me and I found it compatible with a wide range of guests. Linux guest support in HyperV is a joke. Virtualbox sucks for professional use because the functionality locked behind the extensions they force you to download is an invitation for Oracle to begin harassing for licensing with the threat of a software audit if you’re big enough a target.
I don’t mean for this to become a Linux vs. Windows thing. I have reasons that I need to use Windows. Though that’s not to say I’m not pushing for more Linux. Windows 11 is a big enough reason to ditch windows.
The thing is that’s what they want. They all want to be feudal lords.
