100% agree - the whole "bridge makes a difference tonally" is primarily BS. Here's the most realistic/rational aspects about a bridge being a contributing factor; 1) correct location of the bridge so saddles can be correctly intoned. (re: original '63-65 T-bird bridge
incorrect location) 2) ability to dial correct height and string spacing, and 3) having a bridge that doesn't fall apart when changing strings. (YOMV on this one)
Having said this - other than simply screwing a bridge to the body - there
are more sophisticated ways a bridge (any bridge)
can affect the sound of a bass - but that's another more involved story. Everything else is naked marketing - believe what you wish to. Prime example: a standard Fender bent-plate, individual saddle bridge will deliver the exact sound/tone as has been successfully recorded for decades on hit records/recordings. "oh... that must be a _____ bridge on that bass..."

Spend your hard-earned cash accordingly.
