I know Japanese and have tried to learn the other two. (Didn't have enough motivation to keep going, and besides, there is always more Japanese to learn...) Korean has similar grammar and some words share etymology with Chinese/Japanese, which is why Koreans can learn Japanese so quickly. The pronounciation is harder but hangul is not too hard to learn. I felt like I could have learned Korean pretty well given a year or so. Chinese has completely different grammar, tone system is very hard for most people, no hiragana/katakana (so even simple words like 'Chocolate' are written with relatively complex characters, which you have to learn to read and write). The kanji is mostly the same but there are lots of Chinese-only variants particularly if you go simplified (mainland China) over traditional (Taiwan etc.). I found it quite difficult, particularly the tones. There is a lot of regional variation too, and crucially, I couldn't find any interesting Chinese media and have no interest in visiting the mainland, so it was pointless to continue.
