Carbon-centered radicals are electron deficient species in general--you have 7 electrons instead of the desired 8. This means that to first order, you can gauge the stability of a series of radicals the same way as you would for a series of carbocations. In this case, the tertiary cation and the tertiary radical would be the most stable in their respective series. So, no, definitely don't make a primary radical when you can make a tertiary radical.
