Even though we have a 3D Studio Max license, I’d put my vote towards this as well.
As I mentioned in another thread, if you have a Max license, you can already sort of do everything Datasmith offers, but if you only have Blender, then you absolutely need Datasmith.
Perhaps you could even use Gltf2 instead of FBX for the bridging? It would be great for 3D software in general if Autodesk’s dominance would lessen.
