Pit? well he's not really powerful in any way nor does he have anything to make him worth maining. the only real reason he's hated is cause of spammers.
just like people hate Meta cause they spam or cause they'll say he's broken(he's not and anybody that thinks he is is a dumb@$$)
me though, i hate Peach. and for a simple fact: i can't use her. i'm good enough with every character that i can beat a lvl 9 cpu without resorting to spam, instead using combos and stretegies. but Peach? i can't even beat a lvl 5. same with Melee. i can use everybody but Peach.
