Last time I tried Virt manager, I couldn’t figure out bridge networks and ended up corrupted the XML config for the VM. Skill issue for me I guess

I just looked them up and maybe you are right. But QEMU definitely lacks a GUI config tool that is both easy to use and allows for advanced features like snapshots. So far the only ones I know is GNOME Boxes and Virt Manager, and neither is as good as providing handy ways to configure as VirtualBox. I could probably just write the XML config or QEMU command by the documentation, but next time it could be a different scenario so I have to investigate the docs and maybe a few more forum posts. In VirtualBox, the buttons that do everything for me are always there

Because they are for different use cases. I use QEMU+KVM on desktop for games and 3D CAD software, because of its undeniable performance advantage. But on work laptop, I use VirtualBox to test my software on different platforms. On VirtualBox it’s relatively easy to initialize a VM, configure network, file sharing and device passthrough, and its snapshot feature allows me recreate the same environment for troubleshooting

Over the beginning few years into software engineering and FOSS world, I legit thought Sourceforge is a sketchy software download website
