I like to ask complicated questions, where keywords are insufficient. Google first removed search predicates, making this challenging. Now their results quality is abysmal.
I'm not a fan of OpenAI because of their controversial behavior, but ChatGPT does a great job answering my questions. I can then typically search from there if I need more info.
I have had trouble searching for blogs/sites older than a few years, in particular with image search with all the AI-generated crap that floods the internet now. The same search query in kagi gave me the results i was looking for in the first row which convinced me to do the switch. Otherwise before kagi I was going with google/startpage (uses google index). I tried DDG/bing some point but it was horrible compared to google.
