I own P and currently still own a bongo (not for long) and use to own a stingray.
Like you said they are apple and orange. I prefer P because I'm lazy and just want to plug and go without adjusting anything.
Musicman bass have it own taste and it works well in most music as well in my opinion. The unique tone they got is very nice.
Even stingray, bongo and sterling sounds totally different in my ears.
