Quality is still very important. Aikido is a kind of self-defense. I suggest you practice. Karate requires a high degree of coordination, regardless of speed, strength, flexibility and explosiveness. However, if you are tall, you have another advantage, that is, your legs are long. In combat, your leg skills are more valued, so you can practice karate. As for judo, I don't recommend it. I feel that after practicing for a while, my health is not good.
Of course, Taekwondo is also more suitable for girls to practice (I practice Taekwondo), and the movements are more handsome, but it is not as tough as karate and can't be played with my hands, but there are also many girls in our library.
