I'm just watching the beginning and I think it's a mix of the workprint and the Recobbled Cut... the lack of music certainly makes those first scenes with the Thief and Tack (before the ZigZag entrance) a lot less effective. Even boring, I'd say.

I think that music added a lot.

For the most part, I do like Ogg's cut somewhat better as it tends to stay closer to Williams' version, but the lack of music in those beginning scenes probably wasn't a good idea, since most reviewers will decide whether or not they like the film by how fun to watch those first scenes are.
