I would say chain burn is a better deck than reverse burn, basically because it's more consistent.
The main problem with reverse burn is that it can so easily backfire. If the opponent has either mystical space typhoon or fiendish chain for example, you can easily just loose if they chain it to the activation of your gift cards to either negate nurse reficule or destroy simochi.
However the good part about the deck is that it can much more easily OTK than chain burn since it has access to so many powerful "burn" cards.
