Selenium is distinctly more popular among scientists in my experience. I've only seen playwright at startups.
I've personally implemented Playwright in a large enterprise company. Puppeteer before that.
Generally if you have a lot of legacy selenium scripts it's probably not worth it to switch everything over, but if you're creating a new UI automation framework I've just never seen selenium as a first choice for that.
Don't get me wrong it's still solid technology though.
same in my experience.
Isn't Selenium vs Playwright more a Java vs JS/ES/TS thing?
