What FOUR Hetalia characters would be the most awesome best friends to have?

Which four Hetalia characters would be really fun friends to have? Here are mine:

Italy: He's just such a sweetie! Could have a fun time just acting goofy, a flirty sort of person, and he's an awesome chef that could whip you up a plate of pasta whenever you wanted. Plus, I bet he'd be really fun to hug. :3

Ukraine: She seems like she's a really, really nice character, and that she'd genuinely look out for you. She doesn't seem like a catty sort of girl at all, and I live people that look out for others instead of just themselves.

Hungary: Need I say more? xD Hungary's just... all-around so awesome. She's nice, funny, and if you ever had some pervert following you around, Hungary'd take them down with like, her thumb or something. xD Doesn't she seem like she'd be sort of fun to be around?

America: I feel like he'd play the role of the crazy best friend in a group, and since he's not a very uptight character, you could goof off around him and he'd go along with it. I think he'd make an awesome guy friend. c:


So, what do you guys think? What are your choices and why?
