The use of より/のほうが for comparisons seems straightforward when comparing like with like (e.g. "私の方が彼より英語が上手く話せる"). But I have trouble finding a non-clumsy way to express more complex comparisons, e.g. constructing as phrase like "a person who speaks English better than I speak Japanese".
What are some natural ways of expressing this kind of comparison, where we're not directly comparing the same quality/attribute between the two sides?
