I think its better to have the higher resolution video of the iPhone, with its detail in the shadows and then apply stabilization to it in iMovie. The result then would also be less shaky video and better contrast. 
Obviously you would only apply the stabilization to clips worth keeping as it is a somewhat laborious step, but the option and technology is there for you. HD is definitely the way to go
Lets hope there is an improvement in the white iPhone on stabilization too! I am dreaming of a white Christmas.
