Triggering Unit vs. Casting Unit etc

[tml616]

If you have triggers like this:

• Untitled Trigger 005
  • Events
    • Unit - A unit Is attacked
  • Conditions
  • Actions
    • Unit - Order (Attacked unit) to Attack Once (Attacking unit)

OR

• Untitled Trigger 005
  • Events
    • Unit - A unit Is attacked
  • Conditions
  • Actions
    • Unit - Order (Triggering unit) to Attack Once (Attacking unit)

...is there any difference?

More specifically, is it ever functionally different to use something like "Attacked Unit," "Casting Unit," etc... instead of the normal "Triggering Unit?"

No, it is the same, although 'Triggering unit' is loaded faster as an action by the World Editor, rather than its equivalents, e.g. Hero Manipulating Item/ Casting Unit/ Attacked unit.
