Is fidaxomicin better than vancomycin?

Why is fidaxomicin first line for C. diff?
The rationale for this recommendation is that although initial clinical responses are similar for both agents, fidaxomicin increases the rate of sustained response of CDI by 16% at 4 weeks after the end of therapy, compared with vancomycin.
