My 30yo YNA boy is every bit the bird the stereotypes talk about. Hilarious, charming, loves being the center of attention, but also hormonal, protective, and happy to both make and carry through on threats. He's also about as "tough" to read as a neon billboard. Unfortunately it's one of those flashing electronic ones that only lights up for about 0.2 seconds. So, you CANNOT fail to pay attention to him without consequences. No watching movies snuggled up together here. He warns you very clearly, but you have to be watching.
He KNOWS he intimidates people, and will 100% guaranteed lunge at every.single.new.person he meets. Then, when you jump, he laughs maniacally. Which typically makes all the people laugh. And in that way, he instantly becomes the Center of All Attention, which is what he was after from the start. After that, he will typically accept treats and occasionally allow people to scratch him. Because, again, Center of Attention. He's not much of a screamer, usually he's only loud a couple of times a day for 5 minutes or so... or if he thinks you're talking to him...like when you're on the phone.
Let your attention wander though? Nope. He will bite the one he's with if he can't get to the one he wants. I almost never let him perch on me, and don't have hands-on time (other than head scritches) unless we are the only humans in the room (he knows he can drive off the cats and dogs, so they won't trigger bites), because the chances of him biting go up AND the chances of me being distracted, perhaps by conversation, are also up. He hasn't drawn blood in 7 years, but I do have a couple of scars acquired during the 'learning process.' Now that we have a relationship, even if he does bite, it tends to just be a hard pinch rather than full-power. He loves scratches and to wrestle, and (normally) will let me touch him all over.
TL;DR Hot 3 males are wild animals. They act like it. IF you are willing to respect that and use your smarts to work around them rather than expect them to conform to your expectations of a 'pet,' they can be a blast because they have HUGE personalities.
Just like any other parrot species, it takes a certain type to want a zon, especially a 'hot 3' zon and especially a male. It takes a "leader" type personality who is not going to tolerate bad behavior and/or be afraid of the bird. Amazons need a leader for an owner, not a person who views themselves as human 'equal' with their bird. They WILL take charge if you let them, and that's a surefire way to lead to rehoming of the bird as it becomes more and more dominant/aggressive.
