I think duck duck go is better personally. There are still a ton of Google services id have trouble leaving though. Google photos, Maps, Docs ect. I don't think I could quit google altogether.
Interesting so I guess they use Microsoft ad services and thus send data to Microsoft. I just like their search results because they're less spammy than Google. Also I found Google sensors their search results a bit more. Let's say your trying to find a site for pirate streaming. You'll have better luck with DuckDuckGo.
Sorry, I remembered it wrong… the problem was that DuckDuckGo stopped blocking Microsoft trackers. But it seems that the contract with Microsoft was terminated after the discovery.
