BNA (my home airport - because its SUPER easy, we have valet parking, good bbq and bars, and the Pre-check/A List lines are a freaking DREAM), same with Hartford. I find Midway super easy, Shannon in Ireland, La Guardia I weirdly love. BWI is pretty great, especially for a layover. I like airports in general, the efficient ones really do it for me. I hate super tourist airports where no one knows what they're doing - MCO, I'm looking at you. Get some of those women who scream at people to get their business together down there.
