OK, I put that right (as I'm using multipolygons myself quite a lot): it
depends on the situation. If the fence (line between the 2 areas) is
consisting of a lot of nodes it might be better to use a multipolygon, but
if its just 2-3 nodes, I bet you will never be faster with a relation. You
will still be creating the first multipolygon when I already finished all
polygons ;-)

cheers,
Martin
