Both are open source security options with comparable terms, so the choice comes down to which model of the problem you prefer — compare the descriptions below rather than the licence.
AWS microVMs — a separate Linux kernel per sandbox, booting in about 125ms.
The default answer for running code a model wrote. Under 5 MiB overhead per VM, so per-task disposable sandboxes are affordable.
MicroVM isolation behind the ordinary container API — drops into Kubernetes as a RuntimeClass.
The least disruptive option if you already run Kubernetes: VM-grade isolation without changing how workloads are packaged.
