I have trained in several different styles. Find one with an instructor that YOU like.
I taught for 7 years and all of my students called me by my first name, we laughed, had fun, joked a lot...and always learned. My students also stayed out of trouble. Since I stopped teaching...2 of my students have been in and out of trouble (legally, drugs, etc..). I remember seeing one of their parents out and them telling me that they wished I would teach again...that it kept their kids out of trouble.
