Prussia. He is awesome 8D And I love his uniform *-* (Prussian blue! Or his War of Austrian Succession One. He's got it.) Or Romano, I'm working on him, and it's fuuuun 8D (Well, I find it fun because I actually act like him, and I have tomatoes in my garden and I dance with...What I have done of my cosplay to Oishii Tomato No Uta. But I guess it depends XD)
Or you could do my country, Canada. I love his goggles. But it's purely subjective, haha.
