In theory, at least, all French universities are equally good as they are centrally administered. (They are trying to change this, to allow for local autonomy, but it is NOT a very popular idea, particularly among the students.)
One thing you may want to consider is that generally you won't be admitted to a French university as a freshman (i.e. first year student) until you have finished the first year in a US university. In France, you enter directly into your "major" with no "general education" requirements like you have in US universities.
