TIL there's a KVM backend for VirtualBox. Thank you. Does everything "get saved" in VirtualBox format?
I'm using libvirt on my workstation and Proxmox on my servers, it's effort but possible to transfer the VMs back and forth when I need to, not sure if I could do that if I switched.

VirtualBox KVM uses the same format as VirtualBox proper.

The virtual machine description is not compatible with Proxmox. That said, you can import a VirtualBox environment into Proxmox and vice versa. I have done it.

What you actually import is the “drive” of the VM. You create a new VM in Proxmox (or VirtualBox if going the other way). Then you attach the imported disk to it.

The devices may differ between environments. So they are not exactly the same. But as long as the OS you are visualizing can support both, it works well.

I'll have to give it a spin. My biggest concern is for one of my VMs that occasionally moves, it has 'disk' for both an efi and a tpm.
In any case, I've read enough in this thread that I'm going to see for myself. :)
Thanks for the feedback!
