I'm sure you realize that's a very debatable statement.
I think Atmos is very cool for 3D surround sound, but I think it's nothing compared to going from Pro Logic matrix sound to fully Discrete 5.1 DD/DTS/TrueHD/DTS-HD MA.
The Salient speaker is that Discrete Center Dialogue Channel, follow by the Discrete Main Front L/R Channels, follow by the Discrete LFE/Subwoofer Channel, follow by all the surround channels.
Atmos surround speakers are not the salient speakers.
