For web automation/testing, Selenium has been the de facto “standard” since forever. It’s simple to get started with and supports almost every programming language.
My problem with it has been: It’s good enough, but nothing more. It doesn’t work that well with modern, Javascript framework heavy sites (Angular, React etc). I’m not saying it doesn’t work– just not too well.

I know a lot of people who use Selenium, but I don’t know a lot of people who enjoy using Selenium. (That’s no knock on the Selenium team. They solved a hard problem for lots of devs over the course of many years. Huge impact!) Playwright on the other hand…
