I have two PS5 consoles along with the XSX and the XSS. I find I do most of my gaming on my XSS and I think it is a fantastic machine. I have it hooked up to a 4k monitor with VRR and games look amazing.
I also have an external 1 TB SSD attached and I can transfer games between my XSX and XSS using Network Transfer at gigabit speeds. Microsoft permits XSX|S optimized games to be stored on external memory so for stuff I may want to play any time this month, I have them on the external SSD. For games I have downloaded but I have completed and I am now waiting on future DLC, I store on an external 8TB HDD connected to my XSX. Works for me (I have very slow rural internet so I am hesitant to delete anything I have spent hours downloading).
