It is impossible to answer exactly which is better, because taste is subjective and everyone has different preferences.

Xiangge, on the other hand, focuses on innovation and provides some novel changes in Hunan cuisine. Therefore, you can choose according to your own tastes and preferences. You can try it once or twice, and then you can decide which one is right for you according to your personal needs and preferences.
