i've been giving duckduckgo a try and while it's not perfect so far it's been great on the relevant results department :) there is also startpage but haven't tried it in a while

Helium works just fine for me, even though themaniel already decided maybe someone else can find it good. Essentially Chrome, built on Chromium, open-source and just the good old comfy UI. Cromite on Android if you want a safer Chrome for it too.
