better for the visually impaired (can’t have braille on a touchscreen can you)
less prone to failure (you can use a button if you’re wearing gloves or with a prosthetic hand)
make fun clicky sound sometimes
the only thing I think touchscreens are better for (aside from the obvious) is their ease of sterilization, it’s easier to wipe a flat smooth surface than a button with ridges and grooves
