I like the Tulsa airport. It’s similar in size to DAY, but the airside has been renovated much more recently, so there’s a lot more natural light.
At one point, it was one of the few airports I’d been to that had its terminal-wide music system tied to a jukebox that passengers could use. Because of this, on one trip I got to hear the Christmas song Grandma Got Run Over by a Reindeer… during the month of April.
It does have the oddity of being a two-story airport with arrivals (baggage claim) on the upper level and departures (ticketing) on the lower level—the reverse of nearly all other two-story airports I’ve been to.
