I guess the only difference in the ingredient listing is that in the NSI brand the Zinc is listed as L-monomethionine and in the ON brand it is just listed as monomethionine. I don't know enough about vitamins and minerals to know if it being listed as "L-" makes any difference.
But I do know that I sleep better with the ON brand.
