T/S lenses are for when you want tilt and shift with a small format camera. It seems pretty self explanatory to me. And that sounds like what the OP wants. Stating that 4x5 offers more movement and a larger frame is like stating that a witch's tit in a brass bra face down in the snow is cold. Everybody knows that. It is a given. No need to argue for it or against it. On to the OP's question instead...
