Wind style honestly seems like it would be one of the weakest. All wind style is is generating kinetic force in a given direction. And sure, alot of kinetic force can do alot of damage if focused into something like a rasengan or something more idealized like a planet size wave of wind, but that's just it. Just kinetic force. Like if we're taking each nature release and idealizing it to it's fullest capacity, Explosion release is superior to wind release in everyway. Where wind release is moving air with enough force to generate kinetic energy, explosions are rapid devastating releasing of energy itself, and heat which causes more damage. A planetary size explosion > a planetary size wave of wind force. Explosion release is "Wind Pro Edition" lol
But in terms of the most powerful, it's easily Dust release.
"anything that passes through it (or that is passed through by it) is disintegrated on a molecular level."
All the basic elements have weaknesses to other elements, and that extends to KGs like scorch, which is weak to water still, or ice release which carries over it's weakness to fire, making the degree of effect dependent on temperature. Where one weakness is removed, another remains. That leaves Wood release and Dust release as counter-free. Wood as the added effect of granting the user regenerative abilities, and inherently manipulate and absorb chakra, making it the most powerfully defensive release vs Dust which can disintegrate anything it touches (no caveats), making it the most powerfully offensive release.
Idealized to the fullest capacities, you have the ability to generate vegetation to form physical constructs that can be used for blunt force attacks, the ability to drain all of your opponents chakra, and regenerate from any bodily damage vs a force that makes matter cease to exist. While wood style would be super useful and incredibly cracked at it's fullest capacity, the power to essentially erase matter out of existence to it's fullest capacity is far more broken. And in terms of the actual continuity of Naruto, Dust was deliberately nerfed by having the formation of dust attacks requiring a slow charge up time. Legit, Mu's fight during the 4GNW was just him floating in air charging up one attack for like 7 days LOL. Let any dust user spam dust release like every other nature release style and it would easily be the best.
