No! There are as many opinions as there are building materials. If the stone existed, only that would be used. I myself am a fan of aerated concrete. That will surely call up 10 "opponents" again right away. Poroton also has its justification and, like many things, advantages and disadvantages. Since it was explicitly about soundproofing here, sand-lime brick automatically comes into play. That also has disadvantages. So it depends on the specific situation! I recently supervised the house construction for a then good friend. She wanted interior walls made of drywall (because that's apparently how it's done). I convinced her to use 11.5 cm interior walls made of aerated concrete and she thinks it's good today. There is no opinion! And this, please, should also be taken to heart by the co-authors here and not tear each other apart!!!
