Stingray Replacement Pickup

I’ve got 4 American EBMM stingrays. One of them has some form of grounding issue with the pickup itself. So I’m actually interested in trying something completely different instead of a stock repair. (As I’ve got three other basses that still sound very much like stingrays) what are the best options out there for a full on replacement? The Delano, the Bartolini and EMG stuff caught my eye. But I’d love to get into a different sound if I’m gonna replace all the guts.
