It is different though. Even if the speed of the character is the same, you will never make quick turns like with a Keyboard / Mouse. That's why FPS console footage always feel "underwater" compared to the PC.
I have to say the K/D ratio of Torjb players is impressive, PC or console.
K/D is misleading in overwatch since it counts both kills and assists as eliminations. Torbs turret generally hits several different characters in a fight so he racks up a lot of assists without putting himself in danger.
