FBX is quickly becoming the industry standard file type, even replacing OBJ as the preferred exchange format in some software packages.  The problem with FBX is that some software companies have not been able to adopt FBX in its full feature capacity because of some red tape with the Autodesk FBX SDK.  I know Blender actually had some issues with FBX early on and there are other software packages that simply do not support all the amazing features that Autodesk has packed into the FBX format due to licensing limitations or limited access to the SDK.  In some cases, OBJ is actually more widely supported but lacks many of the higher-end functionality that FBX offers.  I feel like FBX will eventually replace OBJ as the most widely used format.  It already has in the Autodesk and game dev ecosystems, but some software packages may take some time to catch up with that transition.
