> what does OpenUSD provides exactly over different formats

USD is to scene authoring what FBX is to 3D object authoring (though it also can do 3D object authoring).

USD adds complex shading, lighting and cameras, state-of-the-art multi-level instancing workflows, and most importantly, a very flexible way of referencing/layering assets and performing per-scene or per-shot overrides, plus tools (payloads) that enable extremely large scenes to be opened and authored in minutes instead of hours.

It really is pretty groundbreaking and has a ton of momentum.

The other hugely helpful component is USD has a very high-performance rendering architecture written in C++ called "Hydra" that allows for both interactive and non-interactive rendering backends to be developed and switched between at runtime. I can't think of a single commercial renderer that either hasn't already built a Hydra delegate, or isn't planning to.

Pretty much a next-gen RIB. FBX itself was always weird child ever since Kaydara days (untill bought by Autodesk).
