As an MV5-PJ owner (and lover), I occasionally solo the neck (P) pickup for certain applications. But as much as I love my Sadowsky and plan to buy another as soon as I am able, I also recently bought a used 2012 Fender American Standard Precision. It has its own sound. Period. No slam in the slightest to my Sadowsky, but it's just a different sound. Maybe the wood, or the pickups, or maybe all of it. Plus, I generally string my MV5-PJ with Blue Label Nickels and the Precision with flats. So even if the Sadowsky gets close to the P tone in terms of the electronics or pickups, most of the time I can't get where I want to go tone-wise (old school thumpy P - think Jamerson/Dunn) with roundwound strings.
A good used USA Fender P is under $1k, so for ME, it's a no-brainer.
That said, my MV5-PJ gets about 90% of the playing time on gigs these days (mostly pit orchestra gigs and occasional cover band fill-ins). Most gigs, I can get 'close enough' to what I need with just one bass - the Sadowsky PJ. But when I need something different and more specific (and conditions permit), then I reach for my Sterling, Precision, Mustang, or ESP fretless. All just different tools in the toolbox!
