I'm not sure if this is an answerable question without a significant amount of research. Are you having problems with performance? Do you believe those problems are related to binding in some manner? – JeffryHouser

Flex's databinding is very heavy as it uses the magic strings event system that adds a lot of extra code in addition to other performance crap it adds. If your looking for performance bind manually. Here's a very in depth report on your exact question though: http://www.slideshare.net/michael.labriola/diving-in-the-flex-data-binding-waters-presentation
