KE G,
The 529 is going to be your better bet. It is more likely to increase in value compared to the interest rates you are going to earn on a money market account, especially in this economy. Though the 529 is going to fluxuate when the market does come around in 5 or 10 years the payoff is going to be worth it... If your daughter were to get a scholarship you would be able to transfer the account to another child of yours or neice/nephew if you so wanted. Otherwise you would have to pay the taxes on it but still worth the investment...even if you pay taxes on it instead of using it for educational purposes.
Not an expert but I have them for both of my kids and I work in a bank so I know money markets and I know that they are not worth anything right now.
