Yes,there was a time when results were not good enough,these days I only use google if my query isn't direct or if a I need to search for individuals(due to how little they care about privacy,searching email addresses anf names is still ideal in google)

Ddg also has 'bangs'. For example !whois looks up a whois record,!b searches it in bing and !translate translates via google translate. They havr many more :-)
