Mechanical relays are available with normally-closed contacts, whereas solid-state are not (except at very high cost).
Mechanical relays can have interlocked contacts so that you can be sure if one contact is closed then a separate one is open.
Not all solid-state relays can turn off a DC load.
Other than that, I would normally prefer solid-state unless one of the above was important.
Solid state or mechanical? I assume solid state would be better. But I am not sure. I thought I would ask.
