I find that you can make some blanket generalizations about the different parrot species, but it comes down to the individual bird.
I would also recommend spending some time at a rescue if you have one near by. In saying that, I would keep in mind that it might take a little time for an older bird (or young bird for that matter) to open up to you. I volunteer at a place that rehomes birds and I am finding more and more that there are no "inherently mean or bad birds". Since I began volunteering there, 9 months ago, I have seen several birds that were once deemed 'mean birds' become lovely, gentle birds after a little bit of time and trust building. It really upsets me when people write off and give up on a bird just because they label it with a negative personality that they think is constitutional. "He's moody", or "she's a biter" are not good reasons to dismiss a parrot from having any companion potential.
Sorry, that rant was sort of unrelated to your initial question, but I had to get that off my chest when discussing rehomed birds. I would suggest you spend some time with as many birds of different ages and species as you can to find which one would work best with the dynamics of your life.
