Is it time to ditch Flow in favor of Typescript?

Recently, I have been witnessing a lot of projects migrating to Typescript and have to ask myself the same question. Is it time to stop using Flow and start using Typescript?

I've seen a lot of backlash from developers that were using Flow to typecheck their Javascript applications. One was even from a former Flow developer:

I'm dropping Flow in favor of TypeScript... and you should too.

Flow just doesn't give a shit about the community... and I say that having worked on the Flow team at Facebook.

Facebook should drop Flow entirely. It's a bad investment for even them at this point

Then came another one from a friend of mine who's been using Flow for a long time:

OK, @flowtype, @AtomEditor, and Nuclide are dead for me. @code and @typescriptlang FTW.

And then I read a comment from Apollo (GraphQL client) claiming they won't support Flow anymore and are moving to Typescript.

Sure, Flow has a lot of issues and since it's still unstable, it's very annoying to update your app to use the latest version. But I liked the idea to just have static types added to Javascript instead of having to use another language like Typescript.

That said, Typescript definitely has it's benefits like abstract/protected/private classes, methods and properties and there is a great community providing type definitions for almost every library.

So yeah, I am thinking of rewriting my current project to use Typescript.

Is there any hope left for Flow? Does it still have some benefits for which you would not migrate to Typescript?
