If you play on a 1080p tv get a Series S, if you play on a 4ktv get a Series X. Series S ain’t bad tho. It’s nice and compact and keeps up with the X in terms of frame rate and loading time. But it might be worth it for you to spend the extra on the X. The ssd on the X has about 800gb of free space and the S has about 350gb. The X can also play your disc based Xbox one games and Blu-ray movies. And you get 4K graphics. But either one is a good choice.
