Well, it's almost the same all along, but as I already said, transfering chakra gives only a temporary boost which will last only a limited amount of time, until the said chakra expires. Also, even SM can't be taught to everyone, only to the people with extreme levels of chakra which Naruto has always had, unlike Boruto, whose chakra reserves seem to be on an average level (judging by the amount of shadow clones he can create).
