better than modern web browsers for sure. qemu guest escapes are mostly in rarely-used peripheral devices, most recently the floppy driver. for less-trusted guests you can simply disable such devices though. if you say "but what about the defaults", look at the number of new web interfaces though: web audio, webgpu, webusb, webgl, html5 audio/video, several media decoding interfaces... all of them with new and exciting vulnerabilities, most can be disabled but enabled by default.
