Narrowing Down and Ranking (urgent)

[sdfluteguy]

Hey! I tried out the flutes below and just wanted to know which models may be better (in your opinion)? I tried them all and still cannot make a decision.

Azumi AZ2
Di Zhao 600
Sonare Powell 501/505
Amadeus 680



Please, I really need some help aside from "do what feels best for you", cause to be honest, that's all I've gotten so far and I cannot make a decision. Based on specs/sound and all, which of those would be best? Maybe rank them?

Thanks!
