A while back I did a comparison of the code behind the major search engines' landing pages, and found that DuckDuckGo is by far the cleanest, simplest, and most accessible, yet they still manage to make a living on text ads in their results. Another easy way to see the difference is to load each site up in a text-only browser like links. You'll find that DDG has the cleanest interface there, too. I still use Startpage most of the time due to the generally better search results, but DDG is my backup and sometimes finds things Startpage (i.e. Google) doesn't.
