It is not necessarily better, but here are some advantages:
When selecting which program you are importing from some informations is displayed telling you which options you should choose when exporting
In the user menu on the website choose login/register
After registration you can access an interface to see all the licenses attached to your email and the activated computers
If there is no available license left just remove one computer by clicking the cross to free its license
All imported geometry becomes one object (mesh) per material, with the material's name as its name.
When updating the model every new objects that have the same name as an object in the existing link will receive its materials, properties and modifiers
You can now render your updated model!
