I don't like Vader's new line because it doesn't sound like James Earl Jones. I also don't like the whole scene of him going out to his Star Destroyer because it destroys the flow of the action. Compare both versions side by side and you'll see what I mean.
Luke's scream is also terrible because it is the same scream the Emporer let out when Vader tossed him down the Death Star chasm. That does not make Empire better.
