I'm using Qwant and it gives me better results than Google. Even Startpage does and it's using Google behind the scenes.
Google managed to fuck up their personalization so much it makes the results worse (it's almost like they only really care about tailoring the ads /s). And I'm suspecting it's by design, if the results suck the users are more likely to either press the ads or go through more result pages, therefore seeing more ads.
