Well, I can't help for the direct one to one comparaison but for what it's worth, at the Bristol show, I was chatting to a REL rep (a younger chap so probably not senior enough to do twisted reverse psychology with potential customers) who said that personally, he felt that the Strata V did not only outperform the Strata III, it also outperformed the Storm III but he shouldn't say that because the Storm III sells for more so REL make more money out of Storm sales. Of course, this might be total salesman bull**** but anyway...
