Aztlan also has space based weaponry. Any scenario which involves North America turning into a glowing field of glass is not a lose for Aztlan. They lead the world in chemical and biological weapons, have the same nuclear options as everyone else, can drop the same asteroid attacks as any of the other top contenders, and they have the unique ability to gain plot device level powers from large scale catastrophes. Indeed, an all-out nuclear war would involve about 200 million people dying in a very short time, distributed amongst every team. At that point the bunker dwellers in UCAS are left with limited options and the bunker dwellers in Aztlan have completed their Mighty Ritual of Vast Powerâ„¢ and ascended to godhood.
Aztlan isn't a bunch of highly magical blood priests with bones through their nose, it's a bunch of highly magical blood priests who own a frickin space station that uses ion jets to control the weather. This isn't a question of magic versus technology, it's a question of wealth, power, magic, and technology. And the Azzies have you matched or beaten on every one of those axises. The Aztech army is better than you are. The only reason the empire ever loses in the books is because they keep being faced with Luke Skywalkers over and over again who are protected from harm by the needs of the plot. Their actual stuff is just hands down the best.

Aztlan only is "the best" because they are a plot device.
