名詞＋といい（名詞＋といい）

The grammar pattern "名詞＋といい（名詞＋といい）" is used to describe or evaluate something by citing two illustrative aspects. It usually carries the speaker's assessment (positive or negative) of the whole object. This pattern is often used in addition and exclusion contexts, where the speaker is weighing the pros and cons of a particular situation or object. The two aspects being evaluated can be either positive or negative, and the speaker's assessment is often implicit in the context. For example, "このマンションは、立地いい設備いい申し分ない" implies that the speaker thinks the location and facilities of the apartment are both good, but there's nothing to complain about. In contrast, "あの歌手は、歌唱力いいルックスいい抜群だ" suggests that the singer's singing ability and physical appearance are both exceptional.
