Baseline game of Zed is worse than it was in AO 2021. He's making waay to many UFEs on the forehand. The AO surface suits his game better I think.Zverev was returning just as well in Australia. His serve is better now, but his baseline game is probably only marginally better. He redlined to beat Novak in Tokyo. But Novak is looking vulnerable as well. He will definitely need to step it up.
