What is the best martial arts style to learn?

Nigel asked:


I am more interested in a more physical, strenuous style for self defense/fighting.

Can anyone recommend a style, organization, dojo, etc. that they like? It would be greatly appreciated.

I have already investigated a respectable ninjitsu dojo and a place (White Dragon Martial Arts) that teaches Choy Li Fut kung fu, but would still like some input.
