The purpose of virtio-console is to create arbitrary bidirectional, host-to-guest communication channels that bypass guest's network stack (don't require working networking in the guest). But even for using it as the system console, it's a bit better than emulated serial port, because the protocol supports passing console resize events from host to guest.
