This is what I'll say, There are much less exotic styles that will get you fairly competent at fighting quicker than capoeira. Also, capoeira has fallen victim to being more of an art than a combative martial art to many. There are many capoeira practitioners that practice with no interest in using it in a combative form. However, as this MMA fighter shows, the techniques are real, and they are extremely effective when done properly. Lateef Crowder is legitimate as well. He just doesn't compete in actual competition.
