The truth is the Russian skaters made everyone else better. Having said that, I do believe Mao Shimada is competitive with the Russian girls.Just my very, VERY personal opinion but USA hasn't presented a wonderful skater since the Michelle Kwan/Sasha Cohen era, so not even worth mentioning.
A very distant 2nd place in level is from here Japan, but as you said above @Arwen17 now that they don't need to compete with Russians, they are the very best even if the seniors/juniors are very, very below to what we're watching this moment.
