嚣张 is more like aggressive, and always use it to others rather than yourself. 骄傲 is proud.

氣焰囂張 = hot air of arrogrance. 氣焰骄傲 = hot air of pride. As you can see in the translation, the two are difference in meaning.

“囂張” is rooted in arrogance, for sure. You use it to describe someone’s unabashed display of arrogance.

Jake, sounds like you need a better dictionary there : ) By the way, Google translate seem to have it right.
