I am mostly in agreement. I would say that the difference is a night and day difference if you know exactly what to look for. In terms of craftsmanship and finishing, I don’t think that they are really comparable.
Now, whether that matters tone wise is an entirely different question. In terms of playing, my favourite bass is a Premium (after a fret levelling job), and I do think it is an exceptional instrument. however, while the Japanese Prestiges I have are not without their quirks, but out of the box they are the better instruments and the woods and finish are truly top notch—same level as Yamaha Japan or ESP Japan.
In both cases you would get an extremely reliable, robust, and well-designed instrument. Either, IMO, would be far better made than US Fender (or even music man in my experience), and if there is anything to fix it will normally be the things that you have to fix anyways (a fret level etc).
