At searching? I can't comment on bing but duckduckgo is different, not necessarily better. In fact for vague matches and context sensitive terms it's quite a bit worse than google.
Keep in mind this is changing over time. Search engines do not stand still, I keep bouncing between Google and DDG, the former has been steadily decreasing in quality and the later increasing to the point that I now use DDG first.
I'm not necessarily saying your opinion at this moment in time will change, only that you should re-evaluate it occasionally.
