Let me further elaborate a bit with examples: The Crawler bridge is AV and wound rather hot. The sound is full, warm, organic, growly, towards the dark side, yet present and not dull.
The RY bridge is also AV but with a lighter and different wind. It is punchy, screaming, loads of overtones, up front, and generally much lighter.
Here we have two vastly different sounding pickups both using AV magnets. I would assume different sizes and other factors are playing a role besides the wind as well. Both of them however play to different strengths of the AV magnet. The Crawler puts an emphasis on the defined organic low mids and bass, bringing them into focus without loosing definition, using the clear high end for balance. The RY meanwhile puts the high mids and high end cut up front with a wind that is bright, but not trebly as it is largely comprised of harmonic overtones, while the bottom end is just there for balance being clear cut and punchy.
Pickups like the Mule however are very balanced, but also have more actual high end than the RY in a way, because it has a softer, musically rounded quality to it from the magnet. The lighter wind and different wire bring out the high end and I would assume with a AV magnet it could easily get shrill and piercing. The high end on the Mule and other vintage magnet using pubs will also be more open and true to the original guitar tone, while having a certain jangle to it.
Entirely different kinds of high end and playing with the qualities given in a lot of the pickups here. Plus every guitar they are placed in makes them sound entirely different again cause the wood is another factor in that chain. That is why the Crawler usually does not go in dark guitars and the RY not in bright ones.
Oh and then you have beasts like the Emerald neck in the middle of that entire scale which uses a vintage magnet with modern wire to give the organic feel, singing voice, and mellowness together with a modern cut and fluidity.
