It depends on the project how conservative you have to be, and what to emphasize. Generally, this company is very fast moving, so waiting some months could make it significantly easier to gauge if it's a good fit.
It leaves frontend tooling in a great place. All these features like built-in test runners, typescript/jsx support, faster iteration loop are quite convenient. There is still work to do for both runtimes in getting a high level of support for all the front-end frameworks, but there is good progress.
I think deno (made by Deno Company) and bun (made by Oven) are in quite similar situations here, both controlled by companies eyeing deployment services of their respective runtimes as the main source of revenue. Node is in the OpenJS Foundation, so it's in a different situation.
