Aside from Rika, there isn't anyone else who has the content. Kaori is a phenomenal skater but she is often lowballed when she's up against Russians and I don't see that changing. I can make the argument she deserved to be on the last two world podiums but was denied due to others being scored over her... Alysa is a lovely skater but I'm doubtful she'll be able to put serious pressure on the Russians. Even if she gets the 3A and a quad back she'll run into one brick wall labeled "GOE" and a bigger wall labeled "PCS" and, whether she's made improvements or not, she won't be given the scores to be competitive at the top... Bradie doesn't have the content and struggles at big events... Karen doesn't have the content and is too erratic... Amber has a 3A but it's unproven in competition, plus she'll be on the low end of the PCS pool... You Young is one of the best jumpers in the field and she's capable of a 3A and a quad from what we've seen. However, her big elements aren't reliable and she also struggles with consistency. I'd love to see her do well at some point though...
I know people have their feelings re: how Eteri does things but you can't deny she's one of the most successful coaches out there. She produces champion after champion. Her track record with longevity is nonexistent but longevity doesn't seem to be that important in Russia since there is always another skater coming up. As one star falls another rises. Eteri's skaters seem to be averaging about 2.5 to 3 years at the senior level before being replaced. That's a brutal pace but it is what it is and doesn't appear to be slowing down.
Well in Russia figure skating (based on what I can tell) is quite popular and thriving with fans, and the skaters are advancing the ladies discipline technically, the same can't be said for a country like the US, lots of empty seats (pre-pandemic) at arenas, dreadful time spots on TV (which is indicative of no draw to the program) and skaters who have far more stability and longevity in their place at the top of the country aren't exactly doing anything risky to try and advance the sport technically - they are trailing the Russian athletes.
