Spackling of Fermacell fiber gypsum

In that case, there are no problems at all. As I mentioned, I've used it throughout the house when we renovated.
There's a bit more work with these as it needs to be skimming. It's also heavy and creates a lot of dust when you need to cut them. It's also relatively new in Sweden, which is why people choose to use regular drywall. It's definitely easier to work with regular drywall.
In hindsight, I still think it was a good choice as they have very good soundproofing and can handle quite a bit of load.

Great!
Regarding skimming, it's fine, I also skim regular drywall to minimize raking light
