Polystyrene or injected foam insulation: which one is better?

Question

I'm replacing my wood garage door (which is attached to my home) with a steel door (because it's cheaper), but I don't know which insulation to use. Home Depot offers the board insulation and another company is offering the injected foam insulation. Which one should I use.
