I have all of them except Mandy's. I'd say overall, Christina's album was the best, then Britney's and then Jessica's (a little too sugary pop overall, but some good stuff).
This is even an insult.no offense..Christina's debut was the best HANDS DOWN!!..her sound was just so fresh and unexpected especially for that category..Why the hell do u think she won a grammy?? Duh!!..lol
