in the same way as other people before misunderstood rk-mma vs lenshu I think you are misunderstanding the kicking mods, cowmeat im sure will see this at some point and explain in more detail than me, but the gravity in erthtk is higher than in tk, making it a lot less floaty and harder to run, also due to the no dq ring more focus is placed on damage and less on dq.

kickbox is even more diffeeent, the 20 turn frames really change the accuracy and make plain defending more difficult as ayou cant react to all your opponents movements in time.

I wouldnt put aikido.tbm, I dont see it as competitive as thr others mentioned, I would add rb_greykido
