For funsies, I cook up a chart from AniLabs rankings. Please do take it with a grain of salt, because from what I understand, the service is relatively new and there's no archive of the previous season rankings from what I can see (Mai's missing her first week and some barely have any data beside from the ranking itself), and I have no idea what methodology they use to calculate the global ranking.
Anyway, actually, non nips have a somewhat favorable view, all things considered, at least comparative to nips, according to the charts. Satsuki has an edge over Ajisai for gaijin, but that's about it.
