Not OP, but I experimented with QuickJS for my SSG and, on my super slow laptop, it started up about 200ms faster than Deno, but ran about 5 times slower overall (and the binary was much, much smaller). My original motivations were: Deno doesn’t support Raspberry Pi and I was running lots of short-lived processes to support incremental rebuilds using a Makefile. In the end, my requirements changed, so I’m not using QuickJS, but it was very easy to pick up and use. So: portability, startup time, and small code size seem to be the advantages of QuickJS.
