I've used Bing for a few years for the free rewards points and purchase rebates, and it has worked very well for me when it comes to normal searches including searches for software development. I very rarely have to turn to Google when trying to look something up, and as you mentioned, sometimes Google honestly gives me worse results. I will say however that I have found the image and video search on Bing to be significantly worse than Google's (which I already have some issues with). Not sure about the other search types like shopping or news since I never use them.
