The major difference is C & D has no abrasive and is "just" a deep cleaner, best used maybe once a month unless you bowl on very heavy oil regularly.
Resurrection has an abrasive and is meant to both clean the cover and to refresh the surface to about 800 grit US. If used with pressure on a spinner, it will leave a light shine.
C&D is permitted ot be used during competition because it will nto change a ball's surface. Resurrection is not permitted during competition because it contains an abrasive and will/can modify the surface.
Both are prime examples of items that you cannot do without, whether you own a spinner or not. They are virtually essential for a good bowler.
