Part of the problem is comparing a mixture of apples and oranges. you cannot run a virtual machine using KVM on its own. KVM is a set of kernel API's and modules that make use of the underlying CPU hardware.
Virtualbox is a complete product that contains its own API's and a bunch of tools to provide a user interface.
Virtualbox is better compared with things like VMware or virtual-manager or proxmox.
virtualbox is like vmware. A complete system. proxmox is just a UI on top of kvm and lxc. Virtual-manager is a UI layer on top of a lot of things (kvm, qemu, etc).
QEMU is a middle wear tool that has been forked by several products to provide hardware emulation but is generally not enough to provide all the features of something like virtualbox or virtual-manager. You can use QEMU to roll your own virtual systems but you then need to manage most of the scaffolding on your own.
Yes qemu has tons of options and features, but not a friendly UI, and certainly not friendly defaults.
Its kind of like comparing gnome or KDE to the x-server.
