I've been using primarily DuckDuckGo for over a year now, and while I agree that for most things it's on par with Google, it's much worse on obscure stuff and on regional stuff (Norway in my case).
That said, I think the parity on most searches is partially due to Google sucking more than it did. Often the thing I'm looking for isn't in the top 10 hits in either.
Yes, I came to the same conclusion. DDG doesn't feel as good as Google once was, but Google is almost unusable now, the entire first screen is almost always 5 paid placements and 5 SEO scam sites.
