Generate from Template vs. SSRS

I just found out that there is “Generate from Template” feature in some forms namely Quotation, SO, PO, Vendor, Customer that users can create Template from add-in in ms words and publish to AX to use in these forms.

So for those forms, users can print either from “Generate from Template” or from SSRS on those forms, can’t they?

And if they can, for developer what is the rationale to chose between 2 methods?
