Google's interface seems to have improved recently, now that they have removed the duplicate left-hand column and put the options on top.
As for search results: I tried DDG again last week, and was shocked by the poor quality of results compared to google, bing or yandex. Search for "html table tag" and you'll see no w3schools or MDN results. Instead a lot of other, crappier sites. Google, yandex and bing all show w3schools and MDN near the top, so DDG must be filtering these results (which is ironic, given that they say they don't put you in a "filter bubble").
