I used DDG as my default search engine for several years, but I kept having to go back to Google because it was consistently more reliable even though it has more crap. I hear Kagi is great but I am not signing up just to find out, nor do I feel confident that 100 searches are enough to make a decision about paying for it. I think Google is garbage but I have yet to se anything that is consistently qualitatively better.
100 searches last you a lot longer than you think, especially if you delegate “postal code Wall Street New York”-type searches to Google via “!g” prefixing.
It’ll give you time to get used to Kagi and set up some personal up- and downranks and blocks. Especially together with the Summarizer and Lenses your search result quality will dramatically improve.
No doubt this is true for you, but my search usage patterns are quite different. 100 searches in a day is nbd for me, sometimes I go through that in a few hours.
