Not op but I love kagi. I've tried so many search engine alternatives and always found myself going back to Google (or using g! to get Google results)
Kagi is the first I've tried where the results are good enough (and get better as I tailor what domains I want to appear higher or lower) to not have to rely on Google. I am a pretty avid searcher though and found I need to be on the $10/month plan for it to work out to the cheapest while still searching like I normally do
I love the idea of them but not at that price point unfortunately
