You know that's a blatant lie. Law's fruit was only ever regarded as special because of it's ability to grant Immortality. It's never been built up as some kind of ultimate combat fruit.
Law went from getting demolished by the likes of Doflamingo on Dressrosa, to now fighting against one of the most powerful characters in the series, all because of awakening. A character, who mind you, has the ability to nullify Devil Fruit abilities.
And you're flat out wrong about Luffy's fruit as well. G2/G3/G4..... All abilities that showcased that Luffy's fruit, in the right hands, was an extremely powerful fruit to begin with. With every new Gear, Luffy became stronger and stronger. All awakening has done for him, was take the concept of the Gears, and amplified it ten fold, which was to be expected regardless if it stayed the Gomu Gomu no Mi, or became the Nika fruit.
