Shortcut vs. item link

I plan to store files in Devonthink and want to be able to access them from Curio in project notebooks. I know that creating a shortcut (i.e., dragging with Option pressed) allows me to see a preview of the file. Aside from that (which is clearly a plus), is there any advantage to using item links instead of shortcuts?

Thank you.

Are these shortcuts a feature of Curio? Item links are probably more reliable as they don’t break after renaming or moving the item inside DEVONthink.
