Well, we all have our opinions... and I believe each team has its trademark.

Let me put it this way; There's not a single one that is less than stunning. It's hard to separate them.
You are quite right. However if there was a world championship contest amongst these teams, then this is what would happen.
Thunderbirds and Blue Angels would think that it was a done thing and just a question of who was going to win between them.
The Frecce Tricolori and Patrouille de France would think that it was a done thing and just a question of who was going to win between them.
The Russian Knights would think that they would win, Solid Russian values over Capitalist scum.
The Snowbirds would put on a good show as would the Swifts, but no one would really expect much.
And the Red Arrows. Well, the Reds would not attend, because they already know that they are the best.

PS, it is no joke, they REALLY would not attend.
