For example, the first comparison http://cl.ly/9RHh if you look closely, the list on the left has a slight left indent, whereas the list on the left (new dimensions) is aligned directly with the buttons above it.
The original list looks "better" to me, as it coveys a subtle sense of depth that the redesign removes. The Likeables app look very WP7-metro to me and alien to the iOS platform. Not saying it's worse, but would work better in a properly tiled OS system.
