I think its hard to guage the success of either of the two but if I had to choose I would probably go with Gibson. From what I have seen of him (which I will admit is limited) he's quiet in the net and I like that about him. What that means is he doesnt scramble a lot, plays his angles well and is a big body that covers a lot of the net. He just seems comfortable in there, and for a goalie of his age and experience, that's half the battle of playing the position.
