It's really a crapshoot, IMHO. I don't believe in blanket statements about any class/pedigree of Fender type basses. There are stellar, mediocre and dog examples of everything out there. All things being equal, you're probably more likely to get a good P or J if it is a Fender Custom Shop, Lakland USA, Mike Lull USA, etc boutique bass ... but there are no guarantees. Even if a particular 3K - 5K boutique bass is better than a run of the mill, off the shelf one, then the question is how much better and is the delta between them worth the extra coin to you. That comes down to a combination of your personal financial situation compared to how much it matters to you. Me personally ... while I have a lot of playing experience, I don't have a whole lotta inherent talent so _I_ am always going to be the limiting factor in the performance of any particular bass so there's a threshold where it's going to be plenty good'nuff. I have a coupla Warmoth parts Precisions that I have less than $400 into (from mostly used parts acquired from Craigslist, eBay and TalkBass) that are "to die for" (for what I like in a P, anyway). I also have a bone stock (rare for me) 2013 Fender American Standard Precision that was a floor model that I got offa eBay for $725 that is now strung with a set of Sadowsky flats that is also a killer bass for me. One advantage I have in all of this is that I have setup skills from being an avid FrankenFenderer ... enough where I can usually get a bass to play the way I like, anyway.
