You should get a series X because you can't trust the devs to make the Serie S run correctly.
You will always have to wait for a patch that will never come or play in 720p because the game hasn't been optimised.
The series S is like third parties on Nintendo console. Yes it runs but barely and it's ugly.
Is this a joke post? Do you own an S? 100% chance you don't and have never tried one.
I have 2 X and an S, the S is a viable option and actual runs games surprisingly well.
In the bedroom, at 49", games look great in most cases, especially ones optimized for x/s.
There are also tons of people on this board that are perfectly happy with the s.
The extreme type series s bashing on this board is just a bunch of either playstation hardcore desperate to slam the xbox brand, or the other group of elite xbox fans justifying thier superior purchase of the x, and it makes them feel more important.
(Not talking about the normal people with opinions on value, talking about the nut jobs that just run into threads calling the series s garbage / ruining next gen)
However, if money is no issue, and you have a 4k tv, no reason not to get the X. Small price increase over the lifespan of the console, with better overall performance and storage space.
