As far as ANH goes, as I said before, I had already seen the original version of it. With ANH, I feel that the SE improved over most (but not all) elements that it attempted to improve. But you have to remember this is coming from someone who had seen the SE of it first. My opinion will unavoidably be biased on several things, just as those who had seen the OOT first are biased when seeing the SEs. Here' my thoughts on it:

*I do not like the original voice of Beru. It sounds less motherly and kind than the new voice.

*The original version portrays Mos Eisley as a very small, dirty town. The scene is also very quick in contrast to the SE, and doesn't let you see the city. Once again, the SE seems to improve this by opening up the city, as the SE of ESB did to Clud City. You see more of the residents going about their day to day lives. It seems more like a "living" space port than the original version, which seemed sort of deserted. Plus, I like the fact that he added the Outrider and a STE speeder into the scene to bring in elements from the EU.

*I HATE the fact that Greedo shoots first. Like many have said, it just messes with Solo's character. I think the 2004 edit of this scene improved it somewhat, as it would seem somewhat reasonable to believe that Solo would shoot at the same time Greedo was. Again, I don't care for it, but at least it was an improvement, and Lucas made a compromise with his fans.

*I do not like the Jabba that was inserted for the 97 SEs. That Jabba looked horrible. I do, however, like the scene itself, and I like the 2004 Jabba.

*I am neutral on the fact that he added more stormtroopers to the scene where Han shoots at them in the Death Star.

*The original Death Star space battle seems somewhat slower with the models. The CG gives the shot s amuch faster and more dynamic feel. It gives it more of the feel of a space battle. It was great that he replaced the takeoff sequence as well. In the original version, the ships were merely these white dots that zoomed off in the distance. With the special eidtions, you get to see and hear them taking off, which seems to highten the excitement for me.
