Plaster or Drywall? – GreenBuildingAdvisor

Our home is being designed as (from exterior to interior)…

1.vertically hung corrugated metal siding 

2. coravent rainscreen

3. LP weather logic

4. 2×8 studs with rock wool insulation

5. intello smart vapor barrier

6. plaster or drywall

Originally we had hoped to go with plaster as it is more breathable and more mold resistant. Prices for plaster are coming back significantly higher and I’m wondering since it’s a one time cost, if it’s worth it? I’m hoping to avoid any trapped moisture behind the walls and back of the drywall. Without exterior insulation being located in central WI, I was thinking it would be important to allow drying but maybe it’s not as big of deal as I’m thinking?
