Best form of fighting? Aikido Judo Karate Wushu etc.?

well I am a 14 year old boy=), and I practice Aikido, Tia Chi, Kenpo karate, Brazilian Jujits,Thia boxing, and Taekwondo. All these martial arts are great, and I strongly suggest that you cross train in all of them because then you will have much more knowledge. But if you just don't have the recources to cross train; then I would do whatever you enjoy the most! Whatever you put your heart and soul into will reap benifts, so do what you enjoy and you will be great! Good Luck!
