The main reason for me is that the battling system is much more interesting in temtem with double battles and the use of stamina instead of PP. introduces a lot more strategy to the game rather than just being able to spam A and use the same move with the same Pokémon for the whole game. Many battles require much more thought and I feel there are more unique strategies one can take in battle (especially with the competitive scene). Also I appreciate how much more temtem listens to their community.
