I really prefer the Hipmunk interface to anything else, but being able to select multiple airports is a killer feature of Google Flights for me, and Flight Penguin won't be able to get my business without it. Being able to select a metro area is not a viable substitute: I live in the middle of nowhere, but about equidistant to two airports - one to the East and one to the West. But they're not in the same metro area (or the same state, or the same time zone).
