I am not dissing barts either, but I don't think I've ever heard anyone describe them as anything other than dark, or a synonym.Over the years, I've built lots of different basses. Two of which, I specked with Nordys in them and two basses with Barts. I like them all, I'm not dissing one brand over the other. Bart's sound different to Nordys because they use different magnets in their construction.
I like the Big Singles a lot, but I also like Bart Jazz PU's too. They sound very different. It depends on what one is looking for…which I think was the original question.
