I really like Mission Control, specially two of it's features. First, creating spaces on the fly. Second, dragging an app icon and dropping in another space moves all of it's windows to that space. It's like Apple read my mind! Sweet. Another thing is UI update as a whole. Aqua has been outdated for quite a while. Now all objects look and feel more real. Also I'm enjoying the new windows' subtle lighting and texture, they look like anodized aluminum. But the top feature on my list are the new APIs, of course.
