On the other hand, Sarada was confirmed to have Lightning release already. It was implied that afterwards he easily learned it. After all, it took several days to learn Lightning release and kakashi trained him hard in order to perform Lee's ninjutsu, leaving little time to actually master Chidori.

Also, Sasuke matched Lee's taijutsu in a month, despite the fact that Lee had to train for years. you're just being dramatic for drama's sake. Evidently, copying what you already can do is a lot easier than copying something you've never done before, whether that's taijutsu or lightning release.
