I'm curious where you get the TES part from? Sofia has teeny tiny Satoko-sized jumps, but her technique is solid (thanks, Mishin). Not to mention she's incredibly consistent, I don't think she's fallen this entire season - someone correct me if I'm wrong. Where as Nastia's jumps are often muscled, off axis, and some, like her lutz, look incredibly unstable. I'd say the only thing in her TES that is way ahead is the step sequence. PCS is also not just skating skills, which is what Nastia does better than Sofia. But Sofia is a performer, and has good interpretation of music; you don't have to be lyrical to interpret music, if you're not using lyrical music.
I loved Nastia 17 - 18 season, and that R&J was a masterpiece. And I was shattered for her when she missed out on worlds twice when she really deserved it. But Sofia earned her place last season much more than Nastia has and proved to be a higher performing and more reliable skater.
