A: Having total surround sound, 5.1, 6.1 or otherwise
OR
B: X-rocker chair :)
personally, I'm all for x-rocker, but of course it couldn't achieve the sounds that surround could, in a movie for example. There is much less wiring to deal with, its great for a computer, and it's very comfortable. Take care of it, and it will last a long time.
