while Aikido has the same idea in all traditions they do vary. Aikikai ryu Aikido for one uses more circular motions, and grace. Yoshinkan are brutal. At least from what i saw of a japanese teacher of that tradition. That’s no ‘easy going’. Uke was pounded into the ground.
I suppose if you like attacking styles, Wushu, Bujinkan and shotokan are good ones.
