What Sim character trait is most important to you, and why?

I miss the brave & diva trait. That was always my favorites.
But as for sims 4, I would have to go with romantic. I find it easier to make my sim not fail at flirting with a sim I create specially for her. But as others have mentioned, traits don’t do too much other then story telling . Especially since we don’t have a proper dating/love system like sims 2
