Showcases for sure, given that contests focus more on being appealing during a battle which isn't her strong suit. Showcases having different themes would also keep her interested for the next event. her appeal would go farther with showcases large scale audience voting system too, she has a way of charming people i think lol

Thats not to say she wouldn't try contests though!! it'd be interesting to see her battle while also trying to make it pretty!! It's definitely a step up from normal battles for her.
