Agreed. Over the years, I've broken apart (and stumbled across blindly) different guitar electronics methods.... there isn't necessarily a "right" or "wrong" way... they're just different.
Like tone circuits that are along the pickup path versus the output or in parallel. They react differently to different pickup types and knob settings.
I used to be very OCD when using my super switches about controlling which coils were physically in the signal path with each series/parallel... dropping both ends of a pickup when the pickup wasn't in use. Typically every coil in a strat has one leg sent to ground and they just "participate" when the other end is connected. Both methods work or have their own pros/cons like if you're going to flip the phase of a coil or do series/parallel and need to intercept both ends of a coil.
Caveman logic says the single pickup "sings" the best because there is only one magnet tugging on the string.... this makes me want to replicate his experiment with a couple different size/wind magnet free coils and put them next to, in the middle, and in the neck... with a P90 in the bridge and see what kind of tones and noise cancelling would happen.
