VMware Player is the best by far in terms of GUI and ease of use. With that said:
It breaks once in a while due to kernel module / kernel mismatches that sometimes require manual patching. This is rare but it happens once every couple of years
It may become paid given Broadcom’s corporate history
Virt-manager is pretty decent and it will not break on a stable distro but:
Some of it workflows are far from intuitive
Virtualization via virt-manager (really KVM) doesn’t currently have any 3D acceleration for Windows VMs
Windows driver/guest tools installation and integration isn’t nearly as trivial as it is with VMware
Personally, I’d try using virt-manager because it will work “forever.” If you can’t get something to work and feel overwhelmed, go to VMware for now but long term you’ll likely have to get used to virt-manager.
