The debate about P vs. J is a popular topic - and always will be because they are the two most popular basses on this planet.
The major reason for this confliction and questioning was started by Mr. Fender himself.
The J bass was supposed to be the "High-End" Fender bass - the one you would graduate to "when you're ready"
The J had 2 pickups instead of 1, the J had a "faster" neck than the P, and the J had the "offset contour body",
The J started out with a "more sophisticated" setup like stacked concentric knobs and a fancier string mute system.
Then, the J started "improving" with stuff like a Blocked and Bound neck - and other cosmetic enhancements.
But, the workhorse P never really blinked when the J came around and continued to be more popular than the J.
~~~~~
I guess a good analogy would be: You find a good "partner" who is reliable, pays the bills, not fussy, simple to figure out, and lets you stay in the spotlight. That is the P.
Then comes along a "better" option, but this partner has more buttons to fiddle with, costs more, isn't so simple to understand, gets cosmetic enhancement, and likes to hum along while you play. All the while saying "look at me!"
~~~~~
Now the J is amazing because if you spend the time it can make sounds that the old goat P can't make. And a delicate touch might prefer the thin neck of the pretty one. And masters of the J can make it ROAR like a lioness in the throes of ecstasy.

And so, the answer is:
Long live the P vs. J debate!
