Agree, you can't really classified it as "best", you are esentially comparing apple to oranges.
Many factors come to play, your physical build, flexibility and all that will dictate how well you can stick to an art.
And correction to some of you. In Chinese, "Kung Fu" means "Ability", "Skills" etc, it bascially means "Martial Art". In general, the Chinese Art is distinguished in 2 major style - Sourthern and Northern.
Even if you practices something that was originated from Shaolin, you are still wrong by calling it "Shaolin Kung Fu", because there are different discipline, the 18 Buddah form, San Da, Iron Palm etc.
So make sure whoever is teaching you at least can tell you what style and its origin, I can't agree to someone who simply say "I teach Kung Fu" as authentic
Just as an FYI, because I grew up in a Chinese Art Family (My grand father taught Bah Qi, Southern Boxing, Choi Li Fut and Hung's Boxing), I figure I will correct the use of "Kung Fu"
Thanks
