Aix or Luberon villages

This is our first visit in Marseille port. We plan to join private. There are two options: 1. Aix and south part of Luberon (can not include Roussillon)

2. Luberon villages including Roussillon

Does Aix flea market, similar to Nice flea market? I want to see both Aix and Roussillon, but can only do one.

I haven't been to either, but know people who have. For me personally, I'd do the 2nd. While Aix is supposed to have a nice old town, I prefer small, quaint, picturesque villages. So it just depends on what you want.
