I got my fiancee to trade in 2 of her old Xbox ones for a series S, she thanked me immediately when she saw the differences.
What DarthVengeant says isn’t inaccurate, but unless your wife has the highest demands for graphics, the Series S would be a perfect choice for you if you’re strapped for cash.
Honestly, I don’t see any serious performance issues with this console and it does what it needs to do for the value you get.
I got a series X day one, the X is better, but if I could only get a series S, I would still buy it.
They’re coming out with the new carbon black version of the console which looks better in my opinion.
Overall, I highly recommend the series S.
