This is the active version, right - not the budget "Select" version?
I would say there is no
consensus on either the P or the J set by EMG. They are
similar sounding to the genuine thing but not the same, and they have their pros and cons. I prefer the EMG's and many professionals use them and prefer their sound. Probably just as many pros would never use them. I have the EMG P on two of my basses and I wouldn't be happy if I had to switch to the Fender originals. Really, it just comes down to the subtle differences in tone between the two and which you personally prefer. In my experience, what I perceive as "smoother" tone with the EMG's someone else will perceive as "sterile".
One selling point of the EMG's is they are noiseless and not subject to the same electromagnetic interference as the Fender p'ups without the need for a ground to the bridge because they have an active preamp and are internally grounded. But this also means they require a battery to operate (and when the battery dies the p'ups quit working) and to some people this is an unnecessary hassle.
