While I'd be curious to see it, the scene where Sandman's daughter tells him to stop fighting was rightfully cut in my opinion. Marko needed to stop because he was perpetuating a cycle of crime and violence. A scene where his daughter confronts him works well on paper, but the problem with the deleted scene was that it had Penny talk him down by convincing him that no amount of money would save her. With this information, his decision to stop makes more sense in the moment, but it undermines the point of him standing down. Instead of ending the violence and apologizing to Peter because it is the right thing to do, Marko just no longer has a motivation to be a criminal anymore. That's a small but significant difference. I'd guess it was why it was cut.
Which begs the question of why release it at all. It was an all-new cut that was not significantly different. It was dug up as a new bonus feature for another box-set release, so presumably a selling point, but also not enough of one to really promote at all. Hence my larger speculation that perhaps Sony initially aimed for some kind of alternate Raimi cut, 3.1 or whatever. I doubt they went to the editor first.
Not to slate it. I really enjoy the Editor's Cut. I do think it is better than the theatrical in a few ways, though not enough to convert anybody.
