There is no such thing as a good or bad tone, and you need to choose it according to your preferences and playing style. However, in terms of craftsmanship level and stability, the Japanese harmonica is generally better than the German harmonica, and many enthusiasts report that the entry-level model will have rough workmanship and weak air tightness, while Tongbao rarely has problems in these aspects.
