Playwright can run tests in multiple windows as well as tests that cross multiple domain origins. My team builds a collaborative app where we wanted to cover scenarios where two different users collaborated on the same page. This was easy to implement in Playwright, in Cypress it is not possible. We can open two browser windows with Playwright and simulate two or more users simultaneously editing a page.

Also Playwright is a general browser automation tool and can be used for more things than just testing. For example, scraping website data or generating preview thumbnails for URLs.
