The best bass i've ever owned would be my musicman sub bass. It wins in almost every category. It sounds fantastic, like a stingray because it has stingray electronics, pickups and the same woods as a ray, it plays pretty nicely with the satin neck (though that's going glossy with use), it looks really nice after i changed the pickguard, the paint looks sparkly in the right light and for £350 off the bay in pristine condition i'd call that a bargain!
Before that though i owned a cheap tobias (which i still own) and a jay turser and two staggs so it's not got a lot to compare to but still a fantastic instrument.
The best i've eve played, probably a real ray, they have the sound, the look and the feel of a stingray.... just a really nice bass. I love stingray necks. a little bit fatter than what i might like ideally but the finish on it is a smooth as butter.
