Simulation results showing the comparison between the performance of
different km3 detector geometries are reported. Effective neutrino areas and
angular resolutions are reported for three different geometries based on
NEMO-towers and strings. The results show that the NEMO-tower based detector
has the best performance concerning both the effective area and the angular
resolution isotropyComment: to be published on VVVNT2 proceedings (Catania, Italy, November 8-11,
