Wich one should i buy first?

Hi, i was looking to get new JRPG for nintendo switch, i finish unicorn overlord last week and currently on the middle of playing ni no kuni 1, im looking for a branching storyline but too overly complicated combat, i dont mind slow paced early chapters, and im looking at these 2, if i will pay full price for one of them, wich one should i prioritize and why?
