I’ve been trying to use it since 2 months, it depends on what you are looking for, sometimes I like the results more than the google ones but the index is smaller than the google one. They know it and at the bottom the offer links to ecosia, startpage and others. If you don’t like the result you can clikc on those links and you will see the same search but from those search engines.
Meanwhile, if you use a real alternative search engine, one that builds his own index: https://www.mojeek.com/search?q=newpipe
