I think you'll find both models will work fairly well for what you want to do. However I'd probably suggest a Korg arranger because the sounds are Triton based. The Triton sound set would fair well for HipHop, R&B, and music like Depeche Mode.
Sounds and styles are always subjective. I suggest you try to find these models in a store and try them out.
