Gabriel in 1 was great, very solid Belmont character.
Alucard in LoS2 was really great as well, finally using a sword instead of just an evil whip.
Dracula in 2 was actually really fun to play as, but I would say i liked him if only because everything else about that game makes me bitter.
but strictly gameplaywise, Dracula was pretty fun.
Although maybe its just me,. but it feels like counterattacks didnt work, or weren't quite as good as in LoS.
