I think it depends on location. In Paris, a machine usually is quicker, especially for non-French-speaking people. Tellers mostly don't speak English and sometimes the intercom system barely works so even a French-speaking person will have a hard time communicating. On the machine, a ticket to / from the airport is one of the first choices available, after language selection. Of course, if your final destination isn't inside Paris proper, you may have harder time and may need to consult a map since fares aren't fixed.
