Pinyin.
It works perfectly fine with diacritic marks to distinguish tones, in fact when foreigners start with Chinese THAT is how they learn it. No reason they couldn't just get rid of the Kanji and just use pinyin, other than cultural reasons.
BS, pinyin is not effective and takes to much time for reading.
Kanji are perfect, just accept that.
