prx was the bigger chocker, who twice advanced to the grand final from the winner's group but lost, and TH advanced to the grand final but advanced from the loser's group
But, prx had advantage and you can see TH actually fought tooth and nail from lower bracket to grand finals in both shanghai and seoul, that makes it much more impressive than prx tbh
To be fair, TH didnt get any veto in Masters and Champions grand final, unlike prx who had 2 vetos in both finals if we are looking at international appearances
