Not only the "ommhhh" from the special edition sounds like Vader through his mask, but in addition you really recognize James Earl Jones voice what is not the case of the old one.

I agree. The SE sounds more like vader rather a random arg from a dude. Besides the pre SE sounds like someones is spiting after he was smoking for 30 years.

If you all stacked with the pre SE arg i suggest adding a more robot effect to the voice like ady did in ANH:R? I still vote for the SE one
