It was always more of a performance vs song deal when comparing Dancing In The Rain to Más. It kinda seems like Dancing In The Rain got as far as it did in the NF thanks to Ruth's performance, while Mas almost won the NF (with the best possible jury marks and practically a tie for first place in the televote) despite Brequette's rather subpar performance.
We'll never know how Mas could have done (I presume the nervous performance and other issues wouldn't have improved dramatically before ESC) but hey, Ruth's 10th place is more than alright at the very least, so there's that.
