I would have to disagree that Tuck is better in IB, not sure if that used to be the perception? They are definitely peers and if anything, I would actually argue that Duke actually has the edge in this space.
1) Same % of the class going into banking, but greater absolute # of class and alum in the field.
2) Same allocation to BB or EB banks (you can see for yourself on LinkedIn but you can also use the employment report avg. salary as a proxy, and if the same average salary exists it means the same proportion went to BBs). Duke maintains stronger access regional banks (Harris Williams, McColl Partners, etc.) and solid pipeline to Houston for energy (sounds like you want NYC though so might not be relevant).
3) Ease of travel for coffee chats/networking (this will be a crucial part of the recruiting process in the fall).
You can't go wrong here but from an outsider's point of view you are looking at peer programs who both place the same in IB, but have 20k extra and the STEM visa consideration from Duke. Seems like Fuqua makes the most sense here. Feel free to PM
