You make it seem as if the reason for your DDG preference is self evident. What is the big difference to you? Is it that the first result's info box is so far to the right?
Less bloat, instant results, lack of images nobody asked for, and yes, it doesn't waste screen space by trying to fit into a narrow noodle to the middle of the screen.
I prefer Hulbee for its in my opinion more appealing design. In particular, I like that the search results are in the center of the screen and not on the left half.
