Ok, I don't have much experience as a carpenter, some drywall here and there, a couple of kitchens, and various other normal renovations of my own house and apartment.
Chose Fermacell for the ongoing bathroom renovation, seemed too good to be true, approved as a single-layer solution in wet areas, with studs at c/c 60 and supposed to hold 30-60kg per screw. Also cheaper than "regular" moisture-resistant drywall.
Some reflections
The boards are insanely heavy
Dust like hell when cut
Edges/corners don't break like regular drywall
Screws grip tightly
But they are incredibly fragile.
I noticed this when I lifted a board (60x250cm) in the middle, it broke, must be ultra-careful when the boards are narrower, around 30 cm, they bend like a PVC pipe when moved. Scraps 10x100cm break when you lift them from one end. They don't withstand anything, just like tretex, just bend and they break. I don't quite understand how this aligns with c/c 60 and its suitability as a single-layer solution and the claim to hold a lot.
Very happy I put OSB behind anyway and that it's c/c 40 from before.
(In the next life, it will be plywood and regular drywall.)

No comments on this. Have now bought fermacell boards for our bathroom and feel a bit like the writer.
I used Fermacell during the bathroom construction in the basement. Now building a new bathroom on the ground floor and will not use Fermacell boards. Reasons: they are heavy, dusty, difficult to get neat joints (matters less if you are going to tile). It will be plywood and wet room gypsum.
