Ugh the one I'm studying (Japanese) is in the super hard category (2200 hours), along with Mandarin, Cantonese, Arabic, and Korean. The writing system is such a bas making it much harder to read than Chinese despite using (roughly) the same characters. Though it's much easier to hear and pronounce than any Chinese dialect at least.
