I don't understand which model is supposed to be better. I think Carbon is the big model and Hydrogen the Flash equivalent? Only because of a Twitter leak though. Like I have no earthly idea based on the naming.
I guess carbon has a higher atomic number than hydrogen? It's definitely the least intuitive of all the naming schemes...
I thought it was just sorted alphabetically so Argon < Carbon < Hydrogen.
Carbon = bigger, Hydrogen = smaller.
Ignore all other models.
