Invisibility and gap closers are basically the same thing in terms of ganking. They're two different ways of catching an opponent off guard.

You either...

1. Close the gap quickly with an ability, so they can't run away until you're there. Or...

2. You approach, invisible, at the normal pace, and the same thing happens.
