All those changes were made to the design because people were looking for something different or companies trying to make a slow moving product more desirable or cheaper to make. Some people like the ceramic magnet pickups. I'm usually not one of those people, but I have one guitar with them that I like the tone of them. As far as the overwound pickups go, that's just personal tastes. I don't like highly overwound pickups much. but sometimes a slight overwound is a good thing. I listen to a lot of sound samples and videos before I buy pickups and usually from the guy playing in his bedroom - clean - without any effects and recording alterations to doctor the product. Those can be hard to find, but they're out there if you look hard enough. Good luck.
