Original Floyd Rose is a quality floating trem. The Edge III is not. Simple as that.

Avoid the Edge III whenever you can. Ibanez makes the best floating trems in the world (Original Edge, Lo-Pro), but their budget trems are dreadful.
Floyd Rose - screw-collar arm attachment, long string bolts that stick out through the whale tail.
Made of metal.

Edge 3 - push in arm, low profile design so string bolts are just a little proud of the saddles.
Made of cheese.
Actually called Mark!
