Does anyone know what is the difference between 7443 and 3157/4157 bulbs?

Its the shape of the bulb. The 3157/4157 are more bulbous than the 7443. The 7443 is a dual filament and the 7440 is a single filament bulb. The 7443/7440 is a more straight bulb. In my sig click on the chrome amber bulb and you will see what I mean.
