Nothing wrong with the standard bridge, but you have to apply thread lock or cable tie the saddle screws together. How does that tally up? People have made incremental improvements to the original design (including Fender themselves) to incorporate grooves to minimise lateral saddle movement, adjustable string spacing and the like. Don't get me wrong, the 4 saddle BBOT was an amazing second go at it, but these changes have improved bridges in terms of design, functionality and reliability.
I have been known to get my nose out of joint when people spout utter BS about my beloved Gibson basses, but one complaint about the BBOT and watch the "nothing wrong with it, nothing needs to change" trad Fender brigade come out with their pitchforks. Adjustable string spacing? BURN THE WITCH!
(in case the winky smiley isn't enough for you, IT'S A JOKE, which should be obvious given its absurdity)
