It's not an either/or. It's a different model, better for some purposes, but
I don't think it was intended to replace the CIA/AIC model (if it was, it
isn't up to the job: it addresses quite a different context). Actually, the
CIA model has never been complete - where do you fit accountability into it,
for instance? - but it's convenient for educational puposes. There are other
models: Donn Parker's hexad, for instance, adds control/possession,
authenticity, and utility to the mix, though opinions vary on how discrete
they really are...

<heresy>Actually, it doesn't necessarily matter much which model you use:
it's the Way You Use It that makes it useful/less </heresy>
