They are qualitatively the same, but the public and scientific case for ozone depletion is a lot stronger. If I had to guess there is like 5-sigma significance that (1) CFCs damage the ozone layer (2) the ozone layer is worth saving and (3) regulating CFCs will help.

Even if you fully accept that regulating CO2 is a good idea, the beneficial effects of that action will barely be noticeable for decades.
