What is the most efficient/practical japanese Kenjutsu/Iaijutsu?
I have been studing martial arts for many years and done extensive reading and was wondering what people’s OPINION of the most efficient/practical japanese sword school/style is. I am referring to specific JAPANESE styles not ones made up here in the US but this could include modern Japanese ones like the All Japan Kendo Federation forms iai and kendo or traditional koryu like Niten Ichi-ryu or Shinkage Ryu. There is no wrong answer just looking for some argument to back it up.
