I imagine the stunt is a little easier for trooping due to the flat lenses vs. bubble lenses of the hero. But I will let the veterans here comment on that (my opinion is pure theory). Other than that from my research, I find it is mostly personal choice. I went with stunt myself because it seemed like a good place to start. Hero kits are available to mod a stunt after the fact so I don't think you're stuck with one or the other anyways.
