It probably would've been the best if Sakura ended up with Lee.
>Unlike Sasuke, Lee cares about Sakura and is also more mature than Naruto
>Sakura actually treats Lee with respect, unlike Naruto
>It would've been good character development to have Sakura grow from hating Lee because he looked weird to actually liking him for his positive traits
>Lee getting with the girl he liked would be the only win he'd get after part 1
