I learn the Japanese one, and I must say that this book is really clear about the grammar points. In the texts of the major elements of the lesson are framed or put in bold. Thus we find very quickly a concrete explanation to a text that may seem difficult at first. Kanji arrive at a correct frequency which facilitates their learning and glossary at the end of the book is really useful. At the end of chapter exercises complete resume each point of the course but unfortunately there are no solutions that would please the self-taught learners (only downside to this book). A real treat to recommend to all beginners
