Bing results still look like Google's used to, and although its index is smaller, that is slightly less important when Google seems to try its hardest to avoid showing you what you actually searched for. I've been using it more as a result, and also occasionally DDG and Yahoo; whereas for a long time my searches were exclusively on Google, now I find myself using other search engines because of the lack of quality of results and these other stupid changes that happened to Google within the past year or two.
With nearly every browser supporting multiple search engines, and keywords, there's just no reason to exclusively use a single search engine anymore. You can have your browser's address bar search duckduckgo just by using a keyword like "DDG:" (or something even shorter D:) and then typing in your query. Same goes for other engines, or even super niche searches on any website. Makes workflow much easier too, instead of going from Bing/Google/DDG -> StackOverflow, set up a keyword for SO directly. Of course, if the website's search method is mediocre then you're SOL but that's more and more rare these days.
If Bing's results aren't good, head back to the address bar and use another engine, if that's not good try another. So easy nowadays that it's kind of insane to me that there's still so many people who aggressively will ONLY use Google Search.
