Which Korean toxes have been most potent and lasted longest?

As I can't do super frequent top ups since my family member does the injections. I must say I'm kind of disillusioned to see ALL these new Korean toxes entering the market (hitox, Evetox, Rosetox, linetox, Hutox) etc yet, from what ive gathered so far NONE seem to have similar longevity and potency *more noticeable results) like western brands. I've tried Nabota a few times (Jeaveau) and its never lasted more than 4-6 weeks. Usually just a month. I'm not in a position to be able to do frequent top ups (I know 3 months is the norm even with western brands and accept some lags, but id like something that really lasts atleast 3-4 months.
