I think he would choose Armin, because he's always saying that Armin is going to be the one to find the solution, the one who's going to get them out of their current situation.

It's not like he wouldn't be upset at choosing, but if he had a moment to think, Armin would be the long term investment for the betterment of everyone else. Mikasa is important, but she's very limited in what she can do. Armin on the other hand is a bright guy who could possibly save the world.
