It's far more about the fingers and the ears than the instrument. However, if two players are more or less equal then the one with the superior instrument should prevail.
Not all Strads are created equal. Some sound far better than others. Also, instruments made by Guarneri del Gesu are preferred over Strads by many top players. And Hilary Hahn uses a much more recently made instrument from the shop of a French builder (Vuillaume, 1864). She could have a Strad if she wanted, no doubt!
As for Joseph Curtin, I don't know how well he plays and didn't think he was part of the performing end of the show in question. But I'm sure he has spoken with countless top players about desirable and undesirable qualities (some of which are subjective) found in instruments. He otherwise could not have risen to the top of his field.
