"The Da Vinci Code" or "Angels and Demons"?

Angels & Demons is the first book, and a far better one in my opinion. I thought the storyline was much more exciting, though The Da Vinci Code was more thought provoking. In general, I like Dan Brown's style of writing, as it tends to keep the plot moving. I don't know which female character I like best. Both are strong women and I like that about both.
