It ususlly depends on what format you get your data in. I almost always use xml between the server and Flex, so when I consume that data, I use using e4x expressions, which return XML and XMLList.
If I was using a back-end + RPC protocol that didn't steer so heavily towards xml, and was receiving my data as objects or Arrays, I might not be using xml. One note: if you plan to update the data on the client, use either ArrayCollection, or XML, or XMLListCollection. These APIs emit the events necessary for Flex to know to update the visual controls.

An Array (or ArrayCollection) seems to fit the bill in most cases and is very easy to access / update. What is the advantage of using an XMLList assuming that my data is rectangular (no nested children). Is there any performance or other advantages to XMLList? I notice that many of the flex examples seem to use XML and I was wondering what I am missing? Bruce
