The strongest person is always the person who uses the technique, not the technique used by the person. This principle is applicable to most anime, and Naruto is no exception. In Naruto, even the same technique, used by different people, will have very different effects in terms of power.
The most obvious phenomenon of this kind in Naruto is probably the Wooden Gun. Naruto fans also joked about it, such as "the first generation of Wooden Gun conquered the world, and the Yamato Wooden Gun made green". In the original work of Naruto, the first Hokage Senju Hashirama's Wood Release is simply ridiculously powerful.
Yamato, who had transplanted Hashirama's cells, was far behind in Wood Release. Not only was Naruto's rampage suppressing half of the Nine-Tails very laborious, but even building several houses would make him exhausted. Uchiha Madara and Uchiha Obito, who also transplanted Hashirama's cells, are much more powerful than Yamato. Uchiha Madara's Wood Release is almost the same as Senju Hashirama's Wood Release without using fairy magic, and even After becoming the Ten-Tailed Jinchuuriki, Uchiha Madara's birth in the Sacred Tree Realm has surpassed Senju Hashirama; as for Uchiha Obito's Wood Release, it may be because he needs to increase the power of the Mangekyō Sharingan to repair it.
In addition to wood escape, there are also very obvious examples of fire escape and water escape among the conventional five escape ninjutsu. The fire escape ninjutsu used by Uchiha Madara is very powerful. To extinguish the fire with one move, dozens of water escape ninjas need to use water escape to offset it; while the fire escape of others is much worse. Of course, the Fifth Mizukage Terumi Mei's water escape alone can offset Uchiha Madara's ordinary fire escape, which is in sharp contrast to the dozen or so water escape ninjas.
In Water Release, the simplified seals and super attack power of the Second Hokage Senju Tobirama Water Release are far superior to other Water Release ninjas. At the same time, the water type used by Kisame Kisaki relies on the huge amount of chakra, and the scope of the water type ninja can only be ignored by most water type ninjas.
The last thing that impressed the swordsman very deeply was the shadow clone technique.
Do you also know what techniques in Naruto are used by different people, and their power varies greatly?
