depends on the exclusives you want to play, or if you want to play with certain friends. if you want Halo, get an Xbox. if you want Uncharted, get a PS4. if your friends play on a certain console more than the other, or only have one, get that same console. to see what games you think you want to play, do some research. see what console offers what exclusives, then watch reviews. read reviews. watch gameplay and highlights on sites like YouTube or Twitch. if you go on Twitch, some streamers you can chat with to ask more detailed questions about the game. YouTube also has live streaming, but Twitch is mainly for video games. if you want a 4K Blu-ray UHD player for physical discs, only Xbox One X have that feature. PS4 Pro does not play physical discs. both console will stream such content though. for a normal Blu-ray player, Xbox One S can play Blu-ray discs, and the PS4 cannot either. it can only stream the content.
