Yeah, but those first 10 minutes includes Vader on the Tantive, and that's too much awesome. Seeing him come through the smokey doorway, and hearing that music as he does so; then hearing that voice and watching him take charge . . . that IS Star Wars to me. Also doesn't get much more iconic than the droid purchase, the landspeeder, and "Hello there."
Can't go wrong either way, though.
Shouty Vader of ANH was always a bit weird to me. How could that possibly be so, you ask? Well, I had seen ESB and Jedi many times before I ever saw ANH. I think I saw ANH for the first time roundabout 1994.
