This is for 1v1 Supremacy.
1. Japan- OP OP OP
2. Ottoman- Janissary rush is hard to beat
3. Russian- Great rush also
4. India- I still don't know what exactly 10/10 stands for but I have seen the Sepoy rush and it's very good
5. Iroquois- Iroquois are the best natives
6. French- Very versatile
7. Aztec- Aztec have good rush but it still sucks having only infantry (the coyote man and arrow knight are infantry btw)
8. China- China is quite good but require some skills (which I lack)
9. Portuguese- They are so hard to beat because they are so defensive
10. Dutch- Banks are cool... but not that great. Another heavily defensive civilization
11. British- I don't know why I thought they were so amazing, they are very vulnerable to early rushing
[Sioux/Spanish/German: I have never played 1v1 against a Sioux, German, or Spanish player so I can't place them in this list. I think this is strange since I only play 1v1 supremacy now, but I still have never seen anybody using these 3 civs.]
