Sorry, I opened the post thinking the question was genuine, and I find
it is rhetorical.

On the title question, "So which is better french culture or US
culture?", why choose? The world would be poorer without Broadway,
Hollywood, Sartre, or Finkielkraut (just to pick some random things I
know of).

More still, I feel that if you insist on writing off so much of world
knowledge, then your culture is very limited indeed. Having said that,
when choosing what to read, just follow your tastes. But don't ask me
to have the same ones: des gouts et des couleurs il ne faut point
discuter.
