Keep in mind that the special editions still had the "Greedo shoots" change, all the terrible and pointless "Episode 1" flavored CGI added to Mos Eisley, and Jar Jar's voice at the end of ROTJ....Plus, there's the terrible scream from Luke in the SE version of TESB.
However, I will agree that they're "better" than the 2004 versions, but the 2004 versions of each film are "better" than the Blu Ray versions, and the Blu Ray versions of each film will be better than the 3D versions coming out in a few years.
You know what's better than them all though?
The ORIGINAL versions.
