Comparing React Testing Library with Cypress is comparing apples and oranges. They provide tools for writing different kinds of tests. React Testing Library is useful for testing React components, meaning: it is React specific, and it is used for writing unit tests. However, Cypress is an end-to-end testing platform useful for any frontend application not just React apps. Also it is not useful for writing unit tests.

I don't have any strong opinion about the end-to-end testing tools though, but some mentioned Playwright is a better alternative if you are looking for e2e testing.
