I'm guessing the sweet was for your Manhattans -- I'd strongly recommend Cinzano above Noilly Prat, if its available. Noilly Prat dry vermouth is superb almost universally preferred in Martinis, but its the only traditional member of their product line and their other varieties have only come out recently after their purchase by M&R.
Something in me always wants to keep my French vermouths (French being the general term for white dry vermouth) and Italian vermouth (the corresponding term for red sweet vermouth) correct vis-a-vis their countries of origin. Still, as objectively as I can, I think the Cinzano tastes much better than Noilly red in a Manhattan. Kudos for not picking up the standard M&R or Gallo crap most supermarkets stock. That stuff's only okay to cook with so long as no one sees it.
