Check it out for your use case. (Have you used up the free searches?) I've not noticed any degradation for my searches. It's going to be different for everyone.
I used them when they first announced their service. Was a nice experience afaik. QWANT is more like internet on hard-mode.. They don't really give you what you're looking for but close enough.. But I've become more dissatisfied with the results of late.
I'll mull the decision for a while but I'm probably going to give Kagi another try.
It could very well be different for everyone. Maybe I’m a generic bastard and Kagi doesn’t think I’m very interesting, so my results are also generic.
