I'm currently considering buying a console. I found that there are always a few models of the same console present on the market, e.g. Xbox One, Xbox One S, Xbox One X/PS4, PS4 Pro, etc. However, it's not quite clear for me as a consumer to have a more powerful (and hence more expensive) model of a console.
My understanding is that Playstation and Xbox games are designed so that they should work perfectly on either model, and I couldn't find if there are any restrictions or limitations between these models (like a game developed exclusively for a particular model of a console).
Of course there is the feature of playing a game in 4K, but is it the only reason for buying the Xbox One X or Playstation 4 Pro models?
