My experience thus far. Google beats out Startpage when it comes to queries related to programing issues. If I have an error, or some issue Google seems to do a decent job of sending me to the right documentation or relevant Stackoverflow question.
Google also seems to do a decent job if I'm searching for particular commercial services if those services have physical location that it can point me to (Restaurants, brick-and-mortor stores, etc). All search engines seem to fail horribly if I'm looking for contractors/service providers in my area. Try searching for who actually provides internet coverage for your street address and you'll end up with every provider under the sun listed in the results. Try searching for a plumber, electrician, chimney sweep, roofer, etc. and you'll get SEO crap for people not even in your state. I've found going directly to government registries (broadband.gov, Arizona Registrar of Contractors [https://roc.az.gov/]) to be the only way to get around this.
What I've really found disappointing is how search results for humanities related topics have really gone down hill in the last decade. For example, I just searched for "The Rebel Camus." The results are always Wikipedia, Amazon, and then after that an assortment of either encyclopedias, links to Youtube, Goodreads (or similar sites). Used to be, that I would get taken to the personal website of a scholar, hosted at a University, whose life studies revolve around that topic -- links to scholarly papers, coursework, suggested readings on the topic.
