No fair asking the Viburnum questions overnight...
I think neither! That's one of the Viburnum plicatum var./f. tomentosum clones.
the very layered horizontal branching habit shouts Doublefile Viburnum
the fruit sit "way up high" on long peduncles, quite unlike the typical Wayfaringtree Viburnum or Hobblebush
the arrangement of fruit clusters on the plant are along the long branches, rather than out at tips of branches as in V. lantana http://davesgarden.com/guides/pf/showimage/158545
leaf petioles on Doublefile Viburnum are typically reddish like this, and far less tomentose than the other species mentioned
V. lantana is quite tomentose on leaves, stems, buds - this plant is not
this plant's leaves are longer and narrow - and quite serrate - like Doublefile
