Oh yeah, I voted Roar, because while it might be a little underwhelming, at least it flows nicely rather than Gaga's track where she's trying to fit too much into one song; I've heard both of them twice and I can only vaguely remember how Katy's one goes whereas the only thing I remember about Gaga's is that it's very wordy...

I like them both a lot, but roar slightly edges it for me.

I don't get the fuss for either song, both are pretty weak for the artists and for music in general, and neither are very memorable.
