I'm not aware of a benchmark, but puppeteer-extra-plugin-stealth can be detected: https://datadome.co/bot-management-protection/detecting-head...

Crawlee does appear to do the basic checks though, like checking navigator.webdriver: https://github.com/apify/crawlee/blob/master/test/browser-po...

Last time I checked (over a year ago) I couldn't find any public code to make Chrome/Firefox properly undetectable.

That said, going to extreme lengths to be undetectable is rarely necessary, because some sites will serve up CAPTCHA's to real people on clean uncompromised residential connections anyway.
