Google is still my default as 9 out of 10 I get the answer I need quickly. Bing does my other 10% where Google provides junk or stale results.... Google Search really is declining. I'm tempted to move my default over to Bing for month or two just to experiment. On the Maps front, I'm really enjoying Apple Maps as it has less junk - I just want a map!!

I switched my default over to Bing about two months ago and it is surprisingly good. Subjectively I would say it is better more often than it is worse.
