Summary: There are tradeoffs. Both remain great options.

My take:

I'm comfortable with TS, so I prefer its extra power.

But if your team doesn't know TS, doesn't have a history of working with types, or your team and app are smaller, PropTypes remain a great choice.
Oh, and I've shipped many large apps using PropTypes. The apps are reliable. We didn't struggle with PropTypes. They were sufficient.

But in retrospect, I suspect we'd have moved faster via compile-time checks on the large apps.

Compile-time checks tend to speed development.
