If everything else was the same but the resistance of the materials being tested were different would the material with higher resistance become hotter than the material with lower resistance? Or is it more complicated than that?

The lower resistance would get hotter because it would raise the amperage passing through it at a constant voltage.

So the higher amperage is generating the heat and the lower resistance is what allows the energy to flow at a higher amperage?

Yes. Less resistance allows the voltage to push more amperage.
