What poke ball is the best?

The Master Ball is the best Poké Ball in the Pokémon series. It has a 100% catch rate, meaning it will catch any Pokémon without fail. However, it is also very rare, and can only be obtained through special events or by defeating certain trainers. Other Poké Balls, like the Ultra Ball and Timer Ball, have higher catch rates than the standard Poké Ball, but they are not as reliable as the Master Ball.
