OSB, unlike particle board, is to some extent self-healing, meaning it behaves almost like wood.
do you screw the spånet or nail it?
you can both nail and screw spån.

A particle board of good quality is stronger than OSB, but it has a "sharper" breaking point. When it gives way, it gives way completely. OSB, however, is tougher and more forgiving when you screw into it. With properly pre-drilled holes in a particle board, things sit rock solid. Particle boards (and plywood) also have the advantage of being able to be glued to studs, providing an incredibly strong wall.
I was advised against OSB for my house by some carpenters and the house contractor. I have not regretted it. They themselves have chosen particle boards in their own (relatively newly built) houses.

Agree with Johan Gunverth, chipboard is better. I have both chipboard and plywood (plywood in the exterior walls). In a few places, the plywood has warped and the wall has become slightly crooked. Not a big deal, but the chipboard is smoother and doesn't move as much. Furthermore, the house has moved quite a bit and there have been small cracks here and there in the corners and wall/ceiling. However, not anywhere on the walls, which indicates that it is stable, with small movements in the chipboard plus plasterboard construction.
We have also not gotten cracks other than in corners and in joints between plasterboards, nowhere has it warped or behaved strangely due to the OSB boards.
But can chipboard really handle having cabinets screwed into it for storing things like china, i.e., heavy items? Admittedly, there are several attachment points, and it's perhaps unlikely that all screws would come loose simultaneously? You also do your best to find the studs behind them... It feels safer with OSB or plywood behind, or do you think that's just unnecessary?

The gypsum board distributes the forces quite well. Even for chipboard. If the fastening is done correctly, it will be strong regardless. The correct fastening is NOT a drywall screw straight through gypsum + chipboard.
