I gotta go with the F-18. Any Navy out there want to pipe in?

If you don't mind someone volunteering an opinion, I think the F-16 is one of the prettiest airplanes ever built, but the F-18 is a badass. One time I was working at Cecil NAS and for some reason there was an F-15, F-15 and an F/A-18 parked together. I love them all, but I liked the Hornet the best.
