I use Startpage and it feels like I always get the results I want even when I don't use perfect prompts. Just recently I got a three month free trial for Kagi and the results were better than google in my opinion, or at least less cluttered with "possibly related things" that are just ads in the end.
I switched to exclusively Kagi on my phone and it's been a pretty pleasant experience. Not perfect, but fairly serviceable. You're right, it's way less cluttered. Going back to Google can sometimes be very jarring.
