If they had a good show? Hell yeah.
Did they win? No.
Call me biased, but I liked Sony's conference despite the boring filler. Last Nintendo console I've owned was a second hand N64 with Super Mario 64 and some other games, and I loved it. While I've played Super Mario Galaxy at my cousin's Wii, I didn't feel compelled by it or the controllers. Yes, this is a different console with new games and probably newer experiences, but nothing from the conference, except Mario Maker, makes me want to buy a Wii U. Neither Zelda nor SSM.
