Drag and drop an image into a markdown file vs "copy item url" and then paste?

If I am wanting to embed a jpg file (that is also stored in Devonthink) into a markdown file, I note that I can drag and drop and end up with this for example:

![my\ image](attachments/my_image.jpg)

Alternatively if I “copy item url” and then paste, prefixed with an ! to embed the image, thus:

![my\ image](x-devonthink-item://1E9F4D9C-7E40-4416-B4CE-B9EDFEE37DFA)

Is there a practical difference in either of these two approaches?
