They are all different and unique, it depends what you want out of the game.
NNK2- easy to learn hard to master combat I hear
Nier: Automata- a very unique game with the way you must beat this game
MHW- Great with friends, intense and satisfying combat
Persona 5- Also satisfying combat, great story and music.
I also recommend Nioh, great JRPG mechanics and fun combat system.
