Cloudflare works much, much better than Google - Google captchas for me, on Tor, are flatly impossible, always. They never let get through, no matter whether you get them right or wrong. You always get "try again".
The problem I do have with CF is their captchas seem to require human interaction on the page, and this makes getting through them problematic when you open half a dozen tabs, and each loads a CF captcha, and you have to move the mouse around for ten seconds just to get the captcha to load, and loading is not reliable. Often you need to reload the page. It's this type of performance, and poor performance, which is breaking web-pages for me.
