I always preferred the original way the scene was done where we couldn't see who was shooting and certainly not who shot first. It was just an explosion making the scene more intense, not knowing who got blasted, and then you see the smokey corpse of Greedo. It isn't until that point that you surmise that Han shot first. Intense stuff.
With the SE change, the scene is so boring you don't even pay attention to what's happening.
