The internet is the written form, but one published online rather than in paper. It therefore makes no difference.
A book is published and then takes time, many years normally, to update. So can be out of date very quickly.
The internet can be updated and edited as many times as one needs and on forums like this very collaborative rather than the work of one person.
So if I were to reason what is a superior source of information then it is the internet.
