Comparing Cheng's works with those of Hsiao Tai-jan, classical singer Chen Shu-chiao says that Hsiao's lyrics are all Taiwanese poems, and the melodies are in an orthodox Western classical form. When performed in the classical style they are extremely beautiful, but they are a little too difficult to be widely sung by ordinary people.
聲樂家陳淑嬌比較鄭智仁與蕭泰然的作品表示，蕭泰然的詞都是台語詩詞，曲子也是正統的古典音樂形式，以古典音樂的方式表現非常優美，但在民間傳唱難度則偏高。
