Not sure online but in person announcers are kinda bad too. The easy tricks they know but I remember them calling a flex flip and scarecrow and a hand full of other ones. I think the judges just tune them out.
Better question is stone vs Johnston K. Trick count or difficulty. Its not easy to go for a long period of time, then again with these motors it helps. Those big flips and one hander/leggers take more than just motor. The first round I thought stone won off politics, the second round just got boring to see a high trick count and low difficulty. IMO round one trick count, round two showmanship and difficulty, round three both and something you haven't shown yet...
