This has been a a tough one, Google gives all ad-focused results, and DuckDuckGo gives crap results (imho)
I did find Kagi recently but they charge after 100 free trial searches, and I'm considering paying for it because it's so good. Best results I've gotten anywhere in a long time.
Thanks!
Ecosia isn't ad free... And if you using them ad free you're just hurting them in their mission.
