Super Punches!

There are several characters in fictional who have a punching ability that exceeds their normal strength by quite a bit. This thread is to determine which super punch is the best.
From Dragonball Z:
Son Goku's - Ryu-Ken
From Bleach:
Chad's Right Arm of the Giant and Left Arm of the Devil
From S-cry-ed:
Kazuma's Shell Bullets and Shell Bullet Burst
From Big O:
Big O's Sudden Impact
From GaiGaiGar (Final):
GaoGaiGar's Broken Magnum/Phantom
From Mazinkaiser:
Mazinkaiser's Turbo Smasher Punch
From Fist of the North Star:
Kenshiro's Hokuto Hyakuretsu Ken and Hokuto Senretsu Ken
From Naruto:
Choji's Partial Multi-size Jutsu
Sasuke's Chidori
Kakashi's Raikiri
(I'm probably not getting all of them, so, if you can think of any other super punches, feel free to mention them)
How would you rank these various super punches in terms of (a) power, and (b) how they improve the user's base strength?
