I didn't read all the reactions to the original post, but I too really liked cover-flow and used it when I was loading in photo's from my SLR, or when I forget the filename of some PDF but knew what the cover looked like.. It's the little things 
So far I have found no use for the new Gallery View, but I'm always looking for new ways to improve my workflow and wouldn't be surprised if it takes me up to a year to effectively incorporate it into daily use.
As for a replacement -- I am now using the Default Icon View and use Command + "+" to enlarge the icons so I can scroll through the content. It's actually quite nice.. Maybe cover flow has become less useful as stuff like preview-thumbnails have gotten more reactive and usable, these used to take forever to load if I remember correctly.
Edit:
The effective workflow:
- Open Finder Window
- Command + 1 for icon view
- Command + "+" (several times) for enlarged icons
