It depends on what is most likely. Are you transmitting power in an area where lightning is likely to strike? If so, then a surge arrester is the correct answer. If you expect a lot of inductive loads to be attached, then a surge capacitor is the correct answer. If both are true, then both apply. Remember that a surge will typically be absorbed by some of the voltage conversion transformers.

How 'safe' do you want to be? It cannot do anything but good to use both kinds of surge protection. In my opinion they should be built into the same product.
'Better to be safe than sorry' right?
