These are definitely preferable to using straight Google but some of these use Google/Bing to get search results. I’m not sure of the others but Ecosia use Google/Bing for their results and Startpage uses Google. Quant does seem to use their own index but it seems like it was built partially off bing when they first started off. Again, not sure about the others if they have their own index.

PS: What’s wrong with Brits?

I hate arguing and I will fight you on that one! ;)
