I am not sure I am entirely convinced by how you make your point but I think I agree. Here is how I would make the case for it:
The Spaniards had armor and combat formation. Having basic protection and having men march next to you closely must make you quite confident.
On the other hand Aztec fighting style seems to be "Go berserk and attract enemies to you so you can harm them to take them as captive so you can sacrifice them later for prestige". You are actually competing with your fellow warriors to show how brave you are". It seems the culture has optimized for not taking into account fear of death.
That might be a big advantage against other tribes that have the same level of tech than you but haven't bet the farm on militaristic culture but it probably breaks down pretty quickly on armies who rely on "confidence in the collective" rather than individual prestige and have somewhat of a tech edge
