This makes sense because it is based on the same Aureal Chip. As a result, I give the nod to the Montego II because of this feature. The Storm does not have a direct digital in. The card has similar functionality to the Ensoniq AudioPCI and sounds as good. It is a bit quieter on the silent sections.
Connectivity is a concern.
Moreover, you must always change cord settings on the back of your computer which is not always easy. The Storm comes with onboard effects and a 10-band graphic equalizer. I checked these out. The equalizer is extremely simple and would provide very basic equalization capabilities but certainly not enough for high-end digital recording. Similarly, the effects can be used only on MIDI applications.
