Every language was designed organically and is full of exceptions and flaws. I don't think most people realize this of their native language. As a native English speaker with a minor in Japanese, I found Japanese to be quite systematic compared to English. I also believe Japanese is more expressive, which is probably true for many languages. The kanji writing system can be difficult, it is true, but there are nice parts about it too if you care to think about them. On the whole I prefer Japanese as a spoken language to English and wish I was better at it. Writing could be argued either way.
