I actually had forgotten the actual sequences for both of these. Came back to me when I watched them.
Anyway, I'd go with Growing of my Heart. I just like the sequence more so than Mysterious (even if it does have Ran as the Angel [like Jodie (wasn't it?) refers to her as]). Song wise, I like both the same, so for the "tie breaker", going by the sequence, Growing of my heart gets it.
Hm...I like Growing of My Heart's sequence better...but I like Mysterious better as a song...
I'm going with Mysterious. I remember really liking it the first time I watched DC through. Plus, there's the added awesomeness of Vermouth kissing a silver bullet.
