* The Romance of Sui and Tang Dynasties is a big book with rich contents. It takes the hero of the crock as a book, and the repeated characters can't summarize the whole book.
* The new Sui and Tang Romance takes the hero of the earthen jar as the main line, and only describes the unification of the Tang Dynasty, and the content after that is not fully expounded. I suggest watching Biographies of the Tang Dynasty and Three Heroes of the Wind and Dust.
To sum up, the two books have different contents and different emphases. The content of The Romance of Sui and Tang Dynasties is more detailed, while The Romance of New Sui and Tang Dynasties only describes the unification of the Tang Dynasty, but the content after that is not fully expounded.
