I prefer sharing nodes.

> Overlapping ways allow a cleaner data model and saves nodes. But editing such ways is quite a hassle. There is currently no function to split nodes so that ways can be separated again. So if the border of the area needs to be changed, the complete area has to be redrawn (at least to my knowledge).

JOSM handles overlapping objects reasonably well (using the middle-click 
menu).  If you need to separate the ways you can add a new node to each 
way individually and then delete the shared node - could be neater, but 
it isn't bad.
