I agree 1984 version is the best. The cast is the most suitable because of their age. Stephen Chow, Dicky Cheung or Jordan Chan were too old for the role. I am not saying their version is bad but if you compare it to the 1984 version, you'll know that its not as good. The chemistry between Tony Leong and Andy Lau in the 1984 version is something legendry in the world of HK TV series. I think I read somewhere that Louise Cha mentioned before Tony Leong is the best Siu Bo so far.
