you cannot get a burpy jazz bass tone from a pj.
Which is why I play a PJ. I also never made peace with Jazz bass tones so I found other options. Doesn't mean I'm right or wrong, it's just my preference.
I don't play a PJ to get a jazz tone. I play one to get broader tonal options, with the P pickup as the starting point. I've never liked the "both J pickups on full" sound anyway. If I did want that, though, yeah, I'd get a jazz. I don't think anyone really thinks they can get that scooped, thinner "both J's" sound from a PJ anyway though. A PJ is its own thing, with its own range of sounds. If they are sounds that work for you, cool. If not, cool.

Those looking for J tones from a PJ are misguided, much like those seeking P tones from a J bass. 90% of the time my PJs are dialed in P-Only. Rolling in the J does indeed change the tone to something different and equally useful and killer. Never is the J/bridge pickup favored or soloed on mine as it is not a tone I personally find pleasant or useful.
