Is Audrey Tautou the leading French actress?

I am a big fan of Juliette Binoche, and I consider that she is the leading French actress today, but Audrey Tautou is becoming a major star. Given her age and number of films that she has done so far, I still think that Juliette Binoche is more established, but Audrey Tautou's career is pretty impressive. Films like Un long dimanche de fiançailles (A Very Long Engagement), Le Fabuleux destin d'Amélie Poulain (Amélie) and Dirty Pretty Things are fantastic. Films like À la folie... pas du tout (He Loves Me... He Loves Me Not) and Le Battement d'ailes du papillon (Happenstance) are also good. Is Audrey Tautou the leading French actress? Probably not yet, but she has a lot going for her.
