kagi is great. It's overpriced, but if you are willing to pay the premium for unlmimited searches (you run out really quickly or aviod doing searches otherwise with the normal plan), it's really good
I'm not a fan of subscriptions, but a search engine is definitely something I can understand requiring a subscription fee. Something like my calendar app? Nope (had to drop... some app because they moved from a perpetual license to a subscription).
