There’s nothing much wrong with a BBOT bridge, other than bring subjectively ugly
I seriously doubt it makes much, if indeed any difference and I bet a good setup is more important to tonal quality anyway
Snake oil - tried it
maybe there’s a difference at stadium volumes but real world ? No, imho
you may get some functional things like threaded barrels for string spacing or somesuch
Just get a straight edge or fret rocker. I spent £11 on a fret dressing kit and solved my own problem that was similar to yours
a truss rod tweak plus two high frets
