While I haven't tested how well the XBOX 360 upsamples regular DVD movies, I would have to say that HD-DVD and Blu-Ray looks better, though it is hard to compare the same movie since I do not have DVD and HD of the same movie.
A couple of things that I noticed when starting to watch movies or documentaries on HD media instead of OTA HD or DVD is that most of the image looks crisper and textural items do not look as muddy. The other thing that catches me is that scenes with a lot of small objects, like capturing a hurd of animals running across a plain from a helicopter, stands out a lot more.
For me, the stand-out examples are the science/nature documentaries, particularly "Planet Earth". It would be interesting to compare "The Matrix" on upsampled DVD versus HD-DVD or "Lord of the Rings" when it is released on HD. I am also wanting to see how much of a difference a Pixar movie would look like on HD, particularly "Ratatouille".
