So after extensive testing, I would argue that C6 Noelle + Stonethresher is at least mid-high S-Tier as a Main DPS with the right team support. But of course the extreme amount of investment required (C6, a 5-star weapon, one or two other Geo supports) probably isn't worth it for most people.

I would put her above pretty much everyone except Xiao with constellations, Ganyu, C1+ Eula and (depending on the team comp) maybe high-invest Tartaglia and Hu Tao.
