Pretty much I think. Look around the forum and there is an experiment that Yummy did .....packed Pot still against un-packed Potty.
I agree with what Twisted is saying .....on a hobby level I doubt very much that you could tell a difference in the finished product.
On a commercial scale with some of the big pot stills used for spirit runs in Scotland there would be some difference in end product......those things are huge and many have lyne arms that point upward for many meters before the condencer, in that case they must get some passive reflux happening.
