I've been using Brave Search[0], and I have to say I've been quite impressed. I don't know if it will be enshitified going forward, but for now they run their own index and have been doing quite well for my purposes.
I'd use Kagi, but I really dislike the idea of my searches being linked to my credit card and home address for privacy reasons. It's a shame, because I do believe that paying a reasonable price for services is often more sustainable and, paradoxically, consumer-friendly than the alternative.
