Well, I don't know too much about Dante, I never played DMC, but if all he's got up his sleeve is a bunch of guns, he's fucked.

As much as I dislike Squall, he's got magic. Ultima, mainly. He can summon demons to kick Dante's ass. He can do his killer "lionheart" attack(I'm guessing this is the name, I can't remember since I haven't played FF8 in years.)
