Ask.com has upgraded their Maps and Directions service similiar to Google with Street, Aerial and Mixed views and an Ajax based interface along with Local Search and Traffic Directions. Though it looks nice, the not so good things are:

1) They currently support only the United States
2) It does not work on Opera 9 TP2 (Competitors like Windows Live Maps and Google Maps work flawlessly on Opera 9)

One can safely stick to Google Maps for now.
