Definitely not Konoha. That place would kill their own and cover it up. That genocide, that racism, that segregation. And directed toward you founder of all people. At lease Kirigakure makes it clear that they will kill you. In fact they don't even pull that shit anymore. Since Mei is their Kage, they've clearly worked on the racism. Suna is too weak and I have no intention to like in a dessert. Iwa is full of nothing but lying bastards. They are to treacherous, though they, like Kumo, care for their own. Kumo is power hungry, but in the end that paid of, as they have the strongest military, rivaled only by Iwa, and the strongest economy. They are like the Narutoverse's version of a first world country in that regard. Not to mention the fact that I'd feel right at home with all those dark skinned people. I just have a problem with their power hungry attitude.
I would live in this order:
1. Kumo
2. Kiri
3. Iwa
4. Suna
5. Konoha
