As an Xbox player, I think Sony will have the next generation advantage, but MS will be in a more competitive position and with an expansion of services on several platforms.
Also this 2020 comes very well with games for Xbox One.
-Ori and the will of the wisps
-Tell me why
-MS Flight simulator (Not sure about this game in xbox one)
Good quantity of games and great variety.
My most wanted game anyway is Phantasy Star Online 2 (Old game i know) and try the Yakuza series in gamepass.
