As someone who took 5+ years of college-level Japanese and majored in (applied) Linguistics, recently learning Korean in my free time has made me appreciate the simplicity of the writing system.
In Japanese, a (non-native) reader can go from understanding one sentence to not even being able to read the next. Sure, there are instances where one may be able to _understand_ a sentence you can't read through inferring meaning from the kanji -- if one couldn't read [水力], but knew both characters (water and power), one could infer that it's "water power" or something hydroelectric. It's a slight advantage to have meaning inside of the characters, however, it's a wonder if the Japanese writing system is too information dense.
Now Korean (and my limited knowledge of it) seems, to me, that it might be the sweet spot. It's relatively information dense (takes less room than just writing things in Japanese kana[1], or hell, even just regular Latin alphabet), but it's quicker to read (and write).
