Ability's are off-gcd and don't use the spell queue at all (they simply fail when you are in animation, macroed or not).
So dunno what you are talking about.

oGCDs can be queued behind hard casts if not macro'ed and if activated near the end of the cast; macroing them is fine, but your cast must be finished before it can be activated.

It's not any kind of game-breaking difference, of course, but it is a consideration.
