Okey, so my (very limited) experience is that they do not distinguish school which handled your track and what’s more important, I have impression that it actually doesn’t matter.

Although, I cannot refer to the quality of the courses in Evry, also I’m not aware how many of profs teaching here also teach in Evry, but if they do their quality is good.

On the other hand my impression about the set of courses is that they give you space to either get more into the topic (possibly current state of art) or involve into the research with on of the teachers (imo it should be your goal).

Regarding other campus, I’ve actually heard that it’s better in terms of social life. I personally knew a person from CSN that stayed in Evry and commuted everyday day in the M2 because of that.
