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.

I like the idea of having Subban, and trying to sell him based off of name value. Though I'm not sure how much people will look into the WJC, which could change the perceived values of Gibson and Subban.

That said I like the situation Gibson is in better than that of Subban, and think he will be the better NHL goalie.
