I, too, switched to Kagi a while back. I was highly skeptical because duckduckgo etc. never worked for me. Instead of finding crap, I found nothing instead. I tried kagi's 100 free searches, and decided that it's worth it. The feature that allows you to block, lower, or raise the appearance of website makes things a lot better after using it for a while.
I don't blindly accept cookies, and at some point noticed just how many health-related pages link to the same lock-out page after denying cookies. So many pages with different fronts that are all the same on the backend of things. Now, none of them even show up in my search results. Slowly, I can actually find useful results, even when searching for something in a field like health which seems to get beaten in nonsense/useful ratio only by few topics.
Does it personalise the result based on your tastes, pages you visit and previous searches?
I tried duck duck go but I don't like how u personal are the results. This last month I switched to bing and it was better. Some years ago I wouldn't belive that bing could be better than Google.
It does not. It doesn’t even keep track of your past searches. They may make this possible in the future, but already have it set as off by default, should it ever happen. It’s honestly, really, really good!
ETA - you can indicate what sources should filter up higher in your results if you want
