I cant say I know that to coment, you would have to show me that chart for me to comment.
It is a few weeks older than what is present on the front page but still you can get the picture.
More than twice as large user base. Quite a bit more than twice the amount of games sold, going by VGC total numbers. Going by weekly sales of games on here most games sell at a 2:1 ratio, some even 3 or 4:1, extremes like FFXV even had a 8:1 ratio.
Btw here’s a link from Metacritic showing the numbers of exclusives over 75 last year.
PS4 = 20
NSW = 13
XB1 = 1
That’s what means not being competitive.
