Series s, its much faster, loading times are non existent compared to ps4 pro, and it runs most games on 60 fps. Its definitely not as loud (I cannot hear it ever) and loading times, stuttering etc have never been a problem. I assume you've already played the PS4 exclusives, a ps4 pro is last gen and won't get games from the next year approximately. A series s is next gen and equiped with the same cpu as a series X. There is no point in getting a ps4 pro if you've already played the exclusives
