"Luffy has a poor fruit but his skill makes it good". That's what people used to say. Now we know it's actually the complete opposite. Luffy had the greatest fruit in the verse this whole time, however his lack of skill is the reason it took so long for him to get strong. This arc proves it. Bonney who is only 12 years old (with regular paramecia) has learned gear 5 in a few minutes, while luffy took years, going through rubbish "gears" which are basically failure attempts of him trying to master the fruit. Even katakuri with his rice cake fruit was better than luffy, the tankiness from the mythical god fruit is what made luffy outlast him, just like with every opponent luffy has battled with inferior fruits
Luffy is not talented in haki either. Only reason luffy learned haki was because he had the pirate kings right hand to spoonfeed it to him, while the rest of the worst generation had to learn it themselves. "Acoc" he only knows because he learned flow from hyogoro. Without him, he wouldnt have that either. It took him near death to awaken the fruit, while kid and law already had it. No doubt if kid, law or bonney had luffys fruit and rayleigh training, they would have easily become pirate king already.
