I've been under the impression for the longest time now that, above all other factors, strings play the largest role in how ANY bass sounds. I've owned many 70's Fender Jazzes and Precisions, and my '11 P-Bass sounds the best of them all. It's also the first Precision I've ever put flats on, so there you go. When it still had the factory rounds on it, it sounded quite similar to all the others.
