iMac Migration

This is sort of a newbie question - I'm not as versed in macs.... I'm updating to a newer iMac. There's been some debate with co-workers on the best migration method. My understanding is in using the Setup Assistant - I could migrate my applications (i.e. ProTools, soft synths, etc) without having to physically reinstall everything. Is this the best method or should I just install ProTools, etc on the new machine as a clean/new install?
