It seems he's talking about the level of immersion, which makes sense. TLoU is supposed to transport you to that world, while SO seeks to create a more arcade type experience, where you're constantly aware that you're playing an over-the-top game. GTA vs. Saint's Row would be a good comparison, as SR constantly shatters the fourth wall with glee.
As for personal impressions, there is a lot I like about SO, from the humor to the customization to the art style to the story but, damn it, zombie horde games do nothing for me. I want to like it but I just can get excited about the game-play.
