I'm preparing for TOPIK II 쓰기 (Writing). Could you please tell me which is better to use in the sentence

Hello everyone! I'm preparing for TOPIK II 쓰기 (Writing). Could you please tell me which is better to use in the sentence "안락사를 무조건 금지하기보다는, 효율적인 보완책을 마련하는 것이 바람직하다" — "~기보다는 ~는 것이 바람직하다," or "~는 방식은 지양하고 ~는 방식을 지향해야 한다," or "~아/어야지 ~는 것은 바람직하지 않다"? I'm confused about which one would be more academic for TOPIK. The sentence should come out as: "It is better to develop effective supplementary measures instead of unconditionally trying to ban euthanasia."
