FWIW, I used Waze for a few weeks but went back to using Google Navigation. I found that the traffic data on Google Navigation was much more accurate and up to date than that provided by Waze, and that Google Nav's display is much easier on the eyes. Waze showed more information, but most of it was irrelevant noise or just plain wrong. All of the social stuff was also very distracting. This was when I was commuting daily on one of the UKs busiest motorways. Also, they send your login details in the clear. I remember taking a traffic dump of my Android phone to see how easy it would be to scrape information at the time... Not that difficult.
