The party is probably over by now, but the question is still a good one. I would bring what you are familiar with. The H9 is not the kind of pedal you want to learn on the fly. With that said, I would go with Sculpt because the tonal potential is vast but useful. The only effect you get is a filter (wah, envelope filter) and an expression pedal is almost required to take full advantage of Sculpt’s capabilities.
As much as I like Eventide and their pedals, they are not simple, powerful, but not simple. Time needs to be spent organizing the H9 to suit your needs. The Digitech RP-1000 is a guitar rig built into a floorboard and is relatively intuitive to use. If you know the unit well, that is what determines “simple” to me.
