I would not call him anything simliar at all
It's only a matter of growth rate, his techniques are either completely inherited and hadnt understood nor developed himself
It's like in the trilogy where Heinrich displays infinitely more understanding and competence over manipulating spirits, obviously he was more experienced, but heinrich actually HAD to try and wasnt blessed with being an angel, he has true understanding, and thus could qualify for something of a 'genius' tier
Luka however, cannot, to qualify for such labels you need to display something other than power growth, which luka acquires completely genetically
Luka hasnt given me anything to believe he actually worked hard for his power, it's like those "talent" "hard work" memes you see in anime communities, luka is 100% on the talent side
But it wouldn't really justify his achievement without nerfing everyone else, hence my conclusion
Gohan is a weird case, because there's dozens of saiyans yet none of them really reached goku or vegeta's level, much less gohan, and for the sake of not going off topic i wont elaborate more on it, thoughi i do have my musings on it, anyways, i wouldn't call them the same example
