There is an assumed aspect that one's choice of freewheel and chain will be the same (I assume Regina Oro) for the Nuovo Record group - and I do not believe NR lasted past '84. SR, yes.

That said, if given the option, I would choose NR over the other two provided it was equipped with a Shimano 600 UG freewheel and chain. If options are limited to the Regina Oro combination, my second choice would be Superbe Pro. If Campag Super Record were added to the list, I'd prefer it over Superbe Pro and NR.
