Less responsive updates (I've gotten things personally corrected on Google maps in 3 days or less, while as of 2012, one of the streets in my hometown on TT is STILL wrong despite this being reported multiple times more than five freaking years ago), very high resource usage (phone seems to slow way down if TT is open or backgrounded), it also uses a ton of your storage memory for map data, and doesn't have the same amount of addon data (street view, reviews, that kind of thing) as Google.
And you have to shell out $50 for it, last I checked.
