So I agree that the quality of Google search is declining, but long story short the others are still worse (IMHO obviously). I tried DDG for a couple of weeks and it was just awful. For almost all non-trivial searches i had to result to !g. I finally switched back after two weeks or so and suddenly I'm much happier with the quality of Google search results. Obviously this is just one man's opinion. I think the technical challenges are big enough to make this a really difficult task.
