What is the advantage of one of these?

It tightens up the timing window on slotted triggers, essentially making is like a single hole trigger plate.

They can also shorten the trigger pull a bit too, as the plate will not reset all the way forward, especially if you have a thicker rod that fits the plate well.

They can also make pre-travel trigger-stops more user friendly when paired with a slotted plate.
