Sony, by a pretty wide margin. They showed more gameplay, had a greater variety of games, and focused more on the future. It made me want a PS5. The Xbox Conference did not make me want an Xbox Series X.
Both had heavy hitters, both had cinematic trailers, both had gameplay, both had indies and smaller games, but only one really showed what next gen can be and the balance was skewed in favour of the PS showcase.
And lets be honest, Sony's history gives me loads more faith in the future of that company than Microsoft has done for the Xbox. Even if both presentations were identical, I'd still have more faith in sony because they have a longer, more consistent history of delivering the goods. This appears to be no different. Even if we're just factoring in the presentations devoid of context or history, the PS showcase showed more gameplay, looked more impressive, and delivered a wider variety of content that interested me, personally.
