I was readin some info on wikipedia and came across this this little passage.
"It was argued among fans that whether the Dugu Nine Swords or the Heavy Sword Technique is more advanced. While there is not a definite answer (from the writer or the book) to this question, there is a reference in the JinYong 100 Questions session during an interview:
Question: Did Yang Guo manage to learn Dugu Qiubai's swordsmanship? How advanced he was in the area of martial arts?
Answer (Jinyong): Partly because Dugu Qiubai had not passed on a complete record/script, his (Yang Guo) swordsmanship was not very strong. Yet his qi energy was stronger than Linghu Chong, as he had been training in the waterfall for sixteen years."
Now it doesn't say that LHC is superior in sword art, but can it be implied?
