Probably the closest to Google Maps. The interface will be familiar, it's easy to switch between OSM, hybrid, satellite, etc layers.

You get multiple options for public transit routes and you can set what time you would like to leave.

Clicking anywhere on the map displays images uploaded to panoramax, the logo from any linked website, wikimedia images associated to that location, reviews for the business, opening hours, etc.
