>>47252313To add to what anon said, even though Easy/Challenge apply a scaling factor to opponents' levels, the Pokémon still have stats corresponding to their original level for some reason, so if you follow the level curve they'll be relatively stronger/weaker.
Challenge Mode does other things like extra Pokémon, max IVs, and held items that might keep it on top overall, but I think Easy might be to some extent harder than Normal.
