I prefer DDG over Google because I seem to encounter less SEO blogspam, but I wonder how long it'll be before such blogspam is tuned for both. Ideally there are conflicting parameters that would make it difficult to game both search engines for any ambiguous query.

Also, this article mentions DuckDuckGo's email protection service, which some (like me) may be unfamiliar with. Seems like a proxy for incoming email that strips trackers, pretty neat: https://www.theverge.com/2021/7/20/22576352/duckduckgo-email...
