Well I haven’t run both of the titles so far, so experience wise I can tell you nothing unfortunately.
But here is what the from the description says
But Renaissance Man is the ultimate free-spirit, so he must not be overwhelmed or else his mission will be in jeopardy. For this reason, the Renaissance Man, similar to StarkQ, has a frame of steel alongside an almost fanatical belief in himself and his creative goals, creating a powerful field that seems to pull others into his vision, allowing him to become a profound thought leader if so desired while protecting him from being overwhelmed by the emotions of the world around him.
Just like Stark has some small aspects of Mogul,
Opinion wise from what I have read on the forum, Stark is about: Intelligence, Seduction, Social Life, Charisma, Produtivity, Wealth etc.
While Renaissance man is about: freeing yourself from blockeges, being able to express yourself freely, honing skills, Ambition, Creativity, Empathy (which in turn helps in being genuine in social interactions).
In the end it depends on which of the following qualities do you want in your life right now.
Hope this helps.
