Well I typically use Vespucci which has the advantage that you have

- aerial imagery as the background so placing nodes or selecting the 
proper building outline isn't an issue,

- house number prediction. That is you only need to manually correct 
numbers that don't fit, and will automatically take the side of the road 
in to account. So if you can see the numbers on the other side you just 
need to walk down the street once.
