My issue with Google is biased censorship and too many garbage results. I have been using Kagi lately and the ability to blacklist domains I never want to see has helped increase the value of my search results.
I do have a question regarding the blacklisting, don't you end up having hundreds or even thousands of blacklisted domains? For YouTube I've lost count of the number of channels I asked YouTube to never recommend. It must be way past 200 by now.
