Remember, first prize designs the main global terminal and runner-up gets the remote concourses.
While I like Gang's design, I would be nervous picking a firm that has never completed an infrastructure project.
I really like Calatrava's terminal but the whole scheme seems a bit ambitious and beyond what the city asked for (and willing to pay).
Fentress and SOM are fine too, though a little on the safer side.
So I'd go Foster for the terminal + Calatrava for the concourses.
Edit: also can we at least get some glass jet bridges in these visions?
