no judo also grapples on the floor. in a comp if your thorw isnt complete then you will have to go to the floor and take them out. BJJ has throws but it is not as throw driven like judo.(i think) you cant punch in judo. and you can use joint locks in judo and jujitsu but no pressure points in judo. (we use pressure points in our jujitsu but im not sure about others) hope i can help.
