I think, bar Edgbaston, it’s because it lacks “the moment”.
Wilkinson scoring the drop goal. Buttler whipping the bails off. The Rose / Kaymer putts. Djokovic putting it in the net. The Mobot.
The 2005 Ashes was incredible but, ultimately, a slow burn all summer and it ended in the drizzle...
As a single moment I don’t think anything in my sporting life has ever topped that 2019 World Cup win, a whole day of nerve shattering tension being released in one moment of ecstasy was just something else.
