What do you mean by "experience"?
My suggestion is first make sure you are of the mindset that you are prepared to care for and nurture any creature that you bring into your home. In many respects this bird will not only be your husband's bird. It will be a part of your life just as much because a large parrot will certainly make you aware of its presence in your home. And I'm sure that your husband will not take this bird with him every time he leaves the house without you...no? A large parrot in the home requires that every family member be on board with the same attitude towards this creature. In other words, that they all want it there. It will be work and modification on the part of everyone.
"Companion" is a term used by the industry and a misrepresentation. Any parrot you bring into your home is programmed to seek out and form a strong bond with a mate. And with that the potential for acting out against any perceived "intruders." As well as the possibility that it will scream its butt off every time your husband leaves the room (if he is the chosen mate).
By and large any pet you bring into your home, especially a non domesticated/wild animal, will have its own inborn temperament that is further shaped by its experiences and the environment. But don't discount nature. Many people make that mistake and fail at owning large birds.
They are long-lived animals whose future personalities are largely unpredictable at a young age. And there is much variability even within the same species - some are simply more vocal than others, others are more nervous and nippy, some can be aloof, others docile and playful. And at different times they will be all of these things.
I hate to say it but a parrot as a "lap dog" for me is a red flag right off the bat. Certainly you might end up with a macaw like that (or moments of peace and quiet) but watch videos of macaws in the wild and you'll see that they're very energetic, gregarious, and feisty creatures (they nip back and forth at each other constantly). Point being is that if you have a narrow expectation you are likely to be disappointed in whichever animal you bring into your home.
Remember parrots have not been domesticated, in other words, genetically modified for desirable pet-qualities over the ages. What the human owner should count on, more often than not, are behaviors that are compatible with the jungle - but in their living rooms. This approach is most fair to the creature you are bringing into your home.
