I can't give a definite answer because this question involves many factors such as personal preferences, historical background, technical level, and so on. Although Alec Su's and Alyssa Jia's version of The Heaven Sword and Dragon Sabre had been adapted and enhanced on the basis of the original work to make it more in line with the audience's taste and market demand, it was not perfect and still needed to be improved in some aspects. In terms of literary value, different versions and adaptation methods would affect the quality and value of the novel. Therefore, different people would have different views on whether they could not be surpassed. From the perspective of TV series production, each version has its own unique advantages and disadvantages. Some versions may be more popular, while others may be criticized. Therefore, he could not give a definite answer. All in all, Alec Su and Alyssa Jia's version of The Heaven Sword and Dragon Sabre had achieved some success in adaptation and production, but it was not impossible to surpass.
