In Jin Yong universe, Chinese martial arts are better than foreign martial arts.
As well, orthodox arts are better than unorthodox arts.
Chinese and orthodox arts are safer, more pure, and more refined.
Whereas, foreign and unorthodox arts are more dangerous, less pure, and less refined.
So then, I ask yee, is it better to have an unorthodox Chinese kung fu, or an orthodox foreign kung fu?
Well, usually foreign kung fu is automatically considered unorthodox, but not necessarily all of them. For example, Jiumozhi's Flaming Blade Palm could possibly be orthodox. Anyway, let's assume that foreign arts can be orthodox.
