Jeffrey found a search engine better than Google.
Based on limited and biased research on my part, Google is tops because, 1) Google is a verb, 2) Google’s results are better, 3) I’ve tried the others and keep coming back to Google, 4) I really want to use DuckDuckGo, but see #3. The interface is easier than Google. I can set DuckDuckGo as a choice in Safari. It does not track users. Maybe it’s a transparent bias on my part, but the actual search results are not as useful as those I find in Google.
