If I remember correctly, normal difficulty should be slightly easier, though I'm not too sure about this. I think the idea is that the harder the difficulty the more levels are required to boost your stats and skills. I think if you understand how to beat the sim disc and can identify which skills are more important in a mission, difficulty shouldn't matter as much as your technique. The only reason why harder difficulty may prove to be quite challenging is because enemies have more health and can deal more damage. And so, in order to effectively get gold on the sim discs, you need to be at a higher level in order to deal and endure more damage.
