All Chinese cultivation systems are pretty much the same, at least until the "immortal" level, then there are slight differences in names, but they are also quite similar. There are exceptions like MGA, where it just goes on and on forever and makes no sense at all. If I have to name a system that makes more sense than others, it would probably be "top tier providence". Desolate Era is also pretty decent. isn't this just an imperial measurement system?
Reverend Insanity was kinda cool At low levels it was just "item" being cultivated to grant abilities At high levels those were combined to make effect I imagined it like blocks (gu) in programming block working in order to grant expected effect
Tales of Demons and Gods was my first exposure to the systems and it was pretty freaking simple. BTTH is the same but with Absolute Resonance that author changed it up. Think he started not doing the 1-10 in Dragon Prince.
