I think Nero is unable to laugh at himself, while Dante can.
This is a major aspect of Dante's character I think: he always makes fun of everything around him (DMC3-4), he never takes things seriously (or never wants to show that he does), even his very fighting style is like a game: he's always playing with enemies and never seems to be really struggling to survive or fearing. "this is what I live for, and I'm absolutely crazy about it! ". What about Nero? He can't even stand being called a kid without becoming angry...
So according to me, Dante is a very exceptional and outstanding character while Nero, even if he is really cool, is more a "mainstream" (sorry for the using this word) and maybe fans were afraid of Dante, who is unique, being replaced by a mainstream video game hero which would behave just as thousands of other heroes do. It has been the case with DMC2, then with Nero and finally with DmC.
so again according to me, there is no hate towards Nero but fear of Dante's loss which manifests through Nero hating.
