I am a casual player, and with all my mates with whom I play Smash Melee, we agreed to ban the
Cyellow joystick smash technique because it was making the smash way faster and we decided to ban this way of winning.
Now that I grew older, I’m still wondering if the yellow joystick on the GameCube controller was only faster but not hitting as strong has left joystick +
Is there any difference between the two hits (damage and impact of how much the opponent will get thrown away)?
According to the super smash bros wiki, the C-Stick is just a shortcut and changes nothing to the damage done or the attack’s range :
In Brawl, the C-Stick (And right stick on the classic controller) can be assigned other control behaviors:
Smash: (Default) Smash attack short cuts, just like in Melee
In other words, when you’re “C-sticking”, the smash damage is exactly the same as the using the combination of
left stick + A, though the C-stick can be executed much quicker.
Additional interesting information can be found about the advantages and disadvantages of both methods:
The C stick is one frame slower than using A and cannot be charged.
The A, on the other hand, can do more knockback (with the charge) and
is easier to repeatedly tap. In short, the C stick is just like using
X to jump or Y to grab. It’s a different mechanism for control that
can be used without any form of bad sportsmanship.
