I have a confession... and a question

I am the actor who plays Skif and I still haven't played STALKER 2 yet. I know! It's ridiculous. Well, I aim to change that. The reason thus far is simple. I don't have an XBOX or a PC. So, I'm finally getting an XBOX. I must! My question for all of you is... XBOX S or XBOX X? Is there a big difference when playing this game? I don't want to go all out on an XBOX X if I don't have to. I only want the XBox for STALKER 2 so I'd prefer to get the S. Thanks in advance.
