Honestly, if they showed more gameplay than Halo's and The Medium's, there'd probably be more things to talk about outside of those games and Game Pass. As it stands, most of the games they revealed are still years away and so there isn't much to talk about that. We also didn't get gameplay from them so again, nothing to talk about.
And also, Game Pass as a talking point is immediately ineffective when you are coming from a country/market that doesn't have Game Pass, so the showcase wasn't really inclusive to all gamers imho.
This notion that somehow Sony showing was way better is really confusing lol, if you watch there trailers next to each other both seem to be damn near the same showing. Nothing mic dropping, some cgi, some in game, what am i missing. Halo which was never a graphical showcase series to begin, somehow made the rest of the show suck ? lol. Just seem like some heavy bias
At the very least, Sony came in with gameplay footage for many of the games, even if they were technically "in-engine"--so whether or not you were impressed by them, there were still loads to talk about.
And also, there were generally a lot of meme material from Sony's press conference (Bugsnax, Cat game!) whereas Microsoft showing so little offers little meme material (except for, again, Halo Infinite)
