Definitely Breakaway. I love 3 or 4 songs on 21 and think they're amazing. Stunning, even. But as a whole, I much prefer Breakaway. I can't listen to 5 or 6 songs on 21, they put me to sleep. I love the whole Breakaway album (except I Hate Myself For Losing you) and it's easily my favorite album of all time.
