It's definitely not perfect but I've found DuckDuckGo to work reasonably well for the kind of quick searches I tend to do from my phone. Plus if it's giving you bad results you can tack on !g to the query and it'll give you the google results instead.
It sure would be awesome if Chrome on Android had it available as an option. But, it's Google.
If you trust APKs from random strangers on the internet, here's my custom Chromium for Android build with DDG support: https://sr.ht/dIQO.apk
Thanks, I tried some Chromium based browsers on the Play Store, but they all have unreliable or even non working Chrome Sync. I'd go full FF, if scrolling on Android wasn't so jerky compared to Chrome.
I started using it because it get's better results. Google says "oh you searched for something vaguely related two weeks ago? let me show you those results instead of what you're searching for now".
Personalized searches can at least be disabled. AMP on the other hand, not.
