Whats is better to import in keyshot - FBX or OBJ ?

focus_method

Hi all,
so fbx or obj type of files,  in doubt when importing files from 3dsmax into keyshot for quick render. Are there any pros and cons ? any advices?

Fbx   saves/opens  quicker  for GB sized files ,     keeps  vertex normals  i.e proper shading ,  keeps object instancing ,   keeps  several UV channels ,  supports  basic pbr materials  much better than obj.   

But can't say something about Keyshot.   Did once an impulsive buying  of Zbrush version  and  uninstalled it long ago
