Doesn't compare to what Itachi can do. Motherfucker can LOOK at you and kill you, and he's what, a high tier ? OP has certain levels of durability negating hax, which is good, but doesn't compare to mind manipulation and shit, doesn't help that its some most proficient users like Sugar are dog shit on the food chain, literally the only way her ability works on anyone would be through a sneak attack or if you have no knowledge on what she can do, very situational. You can argue OP has more variety but it's still not as powerful as Naruto's
You're saying Itachi is a high tier with a broken ability. Well Sugar is a mid tier with a broken ability.
Itachi killing you with a look, THAT YOU CAN ACTUALLY BREAK OUT OF IF YOU ARE STRONG ENOUGH, is very different to Sugar instant K.O wit a touch that CANNOT BE BROKEN OUT OF. And i don't know about you, but killing someone vs Erasing their existence... What do you think is a bigger hax?
Ok, vast difference between country level and planet busting though, can Madara and Guy pull off the latter with sheer strength alone ? . Plus the 3 examples you used are top to god tiers (latter being Naruto). They're not benchmarks for the entire universe.
Well the only person in OP close to country level is Whitebeard and he definitely doesn't do it with raw power. Whitebeard can't swipe away a country busting attack with raw power, he's needs quakes to do that.
My stance on general verse vs top tiers in the verse is this
This might be true.
But the verse is measured with top tiers. Not fodder.
One piece in general has more characters than Naruto so oda has to go out of his way to make more relatively strong people so that his very many characters aren't useless.
The tontatta for example are all able to move faster than the eye can see. That's just their regular speed which all of them have. Yet in Naruto that's an actual speed feat that has to be trained for.
So the tontatta have to be useful to the plot and there's very many of them so oda has to just say the entire race is like Mach 2 in speed as their Base speed. Simply because plot demands it.
And then Oda has to make Sugar faster than all of them so that she is a threat to them and we end up having Sugar who is generally unremarkable in physical stats in pirate standards moving like at mach 5 speed.
See the problem with counting "average pirates vs average ninjas" is that this is just plot.
Actual verse scaling is done with top tiers only because plot affects them much less than fodder
Basically its just plot. The plot of naruto has way fewer people so the power scale looks very steep. From fodder to top tiers is a ridiculously high ascension becuase the story just doesn't care about the people in between that much
Whereas for one piece, just in East blue, there was a whole heirrachy of power in just that one saga starting from fodder like Alvida all the way to Smoker. And those were all shit tiers compared to the stuff happening now.
Lets compare this. In east blue, Arlong was a big deal for managing to topple buildings and essentially destroy a town. In the new world, Randolph, some random Big mom underling was able to do this. Tobble buildings and destroy towns. And RAndolph got One shot by Carrot. See. There's a ridiculous number of people in between Arlong and Carrot and theres a big number of people below Arlong and a very big number of people above CArrot. Oda goes out of his way to give non essential people power to be useful in the plot and that leads to A lot of people being decently strong in Average compared to Naruto.
Whereas compare to Haku, the first big villain NAruto fights the series. Haku is stated to have LIGHT SPEED TRAVEL within his mirrors. This is Arc one villain stuff. Some guy just has LIGHT SPEED TRAVEL in the first arc. The story just doesn't care about anyone in between that much. So you end up jumping from fodder to god tier very fast because no one in the middle matters that much
