The debate about bridges is all over the map - high-mass vs otherwise, aluminum vs brass vs steel, individual saddles vs two saddle-bar (early P-bass), individual-string bridge vs standard/combined, and what the saddles are made of (metal, brass, wood, or plastic). Then there is top-load vs string-thru and imbedded anchor plate/flanges vs standard flush-mount. They all work if installed correctly and offer the required saddle travel. The rest is nuance and individual preference based on ones ear and finally, aesthetics.
