It's hard to compare them because the goals are different. Kata containers seeks to harden container security by wrapping it with a highly optimized VM. Sysbox seeks to enable containers to run system-level workloads (systemd, dockerd, k8s) without requiring complex images, privileged containers, special mounts, etc.

Also, Sysbox is a pure OS-virtualization technology, which means it runs in environments where hardware virtualization is not available (e.g., a cloud VM, since most cloud providers don't allow nested virtualization).
