Flex or Flash?

I can’t decide what i want to use.
I’ve made an admin page using flex adding FAQS to a database plus some other little options.

but for the user i want a FAQS search app.
I initially thought i would use flex, but i’ve come to the conclusion Flex is only quick when using the built in components.

To me flash would be easier to create an app where i could control how things will visually appear…

For example in Flex would it be just as easy in flash if I were to NOT use “lists” and “datagrids?” What if i want to have a “skinless” expand and collapse type menu?
