I don't understand why you're trying to convert this convervation to a nationalistic debate. It is nothing about Turkish radios or Turkey's "overrated" song. These are my personal observations about ESC winning song. I'm arguing the winner song and comparing it to other winning songs of previous years. I don't understand why I have to critique Turkey's entry. It is not 1st, but if you want you can critique it whatever the way you want.
I don't think Euphoria is as specular as Wild Dances, Fairytale or My Number One and of course it's not as much Waterloo. If I prepare a best of ESC ever list, I definetely won't put Euphoria in this list. Following list includes most of best ESC songs ever I think:

By the way, the best of ESC for all time is: UK, Brotherhood of Man - Save all your kisses for me
