I'm looking at this season - Tuk's 3a height and rotation are amazing, even if her landing is shaky and if she were to fall, she still rotated fully. In the practice video, Mao's 3a looks under-rotated, which is a concern.
It doesn't mean that alone will net Tuk the GPF, Mao has other qualities in her skating, but I'd say as of today, Tuk's 3a has better height, speed, rotation so far.
I hope Mao lands a good one, I want to see it too, and her other triples, it'll be amazing.
Tuk is taking a lot of flak for SC for her overall skating, but she did shakily land an impressively rotated 3a.
I don't know if it is more solid (time will tell) however I do like Liza's 3A better. When I watch Mao, I fear fall/UR, with Liza I just fear a fall.
But at the end of the day we gotta look at the whole package and I think Mao really knocks it out of the park. When Liza doesn't land the jumps then she has little to cushion her (though she is usually consistent). Mao still has her spins/footwork to keep her scores up.

Why are you running away? It is on the flat side now, which is a heck of a lot better then on the in-side that it used to be.
