I find the Kagi results to everything I need, and often lead me to more niche personal blog posts specific to what I am looking for. Surfacing small blogs posts is not something I remember getting much of in DDG and I'm really enjoying that.
It may be related to which type of content you search for, field of work or even how you search, but you're certainly not the only one I've heard complain that they need !g way to often for alternatives to be viable.
Google is very good is you need to buy something though. Their ad system yields rather good results, most of the time. Lately I've noticed that they are more and more serving ads for questionable drop shippers and foreign webshops, rather than brands I trust, so they might also be declining in that department.
