Same with Johnny....but if you take a look at sasuke's performance in ..
 * Sasuke vs Bee (mangekyou scenes)
 * Sasuke vs 5 kage (mangekyou scenes..which is kinda the whole fight)

Then take a look at after sasuke got the EMS..
 * In the war
 * In his fight against kabuto..

...You will notice he can use more techniques without any noticable drawbacks, can also spam susanoo..and he lasted the fight then went on as if nothing happened (fight against kabuto).
