I voted B.
Solid show, but many of the interesting releases are far off and most of the stuff they showed were multiplats and timed exclusives.
Forza Horizon 5 was the only thing that I personally felt "Damn, that's impressive" about.
They spent way too much time on FO76 and the fact that they even mentioned Skyrim was a complete waste of precious time IMO.
Edit: Also, ending with Red Fall was probably the worst "... and one more thing"-moment ever. What were they thinking?
Edit 2: Actually the more I think about it I am leaning more towards a C. It was a good games showcase but it was generally pretty weak in terms of Xbox own first party studios. I generally won't take into account multiplats when judging a Sony showcase and when removing all multiplats and timed exclusives it was a pretty weak showing for XGS outside of Forza Horizon 5.
