I am so naive and ignorant. I had no idea that this was a thing to fight over. If you want to win races, go with newest, modern tech. If you want to have fun or enjoy some nostalgia from your youth, use the fun toys from your youth. I have U-brakes, cantilevers, V-brakes, cable pull disc brakes, and hydraulic disc brakes all sitting side by side in my garage and none of them have ever started a fight with another set of brakes.
