pretty much every v flower artist i follow has still been using v flower and not ci flower-- minus a couple real popular once who maybe did a release demo. this isnt to say its proof ci flower is "bad", i think it just shows specific versions of voices are preferred to certain reasons. (and also i imagine some dont want to drop money for a new engine and learn it too). most of these v flower artists, using flower for that specific sound and it works! and i cant really imagine a lot of their styles translating as well to ci flower. i think too many ppl see a new, and quite different voice as the "upgrade" everyone will have to move to when thats not the case.
