Most of my career has been spent building web apps in Rails, Node, a smattering of python frameworks.

Python is pretty great, but the fragmentation of the ecosystem puts it behind Rails imho.

Node is a constant headache and I have seen it be the death of more than one startup. Unless you are using a typed version of JS it is going to be a problem, I can guarantee it.

Rails kinda just works. It isn't as performant as I would like, but for the overwhelming majority of web apps that isn't an issue.

I know it can be hard to find rails devs, so just make them. Hire competent CS grads and train them. If they actually earned their degree it will be easy.

If you are in an executive role at a startup building a web app and optimizing for team velocity it is always in your interests to choose an opinionated framework that has already solved the hard problems for you and imposed structure on your team.
