I also have one of each. Neither of which "chose" me. My TAG I got while she was a baby (she is now 11) and my CAG, I've had just a month or so and is a 10 yr. old rehome. Our TAG is amazing.Very easy going, never plucked a feather, loves to just hang out, is a snuggler, definitely has some words but prefers to mimic noises and loves to whistle. The CAG has a ton of words and phrases, much of which we are still trying to decipher, as we don't know the voices in which it came from and he/she likes to mumble and talk "under her breath!" For a rehome, I think we have been extremely lucky. She has been regurt., putting her feathers forward, and making her little noises practically from day 2 of bringing her home. She is much more needy, however, and our TAG is, though extremely cuddly and not stand offish in anyway, much more independantand able to just "be." Now, of course, this may have much to do with the situations they come from. Birds are like people, all very different, each with their own set of needs, wants, and desires.
****We started originally with TAG because we had not had a parrot before and thought that would be best. My Husband had grown up with a rehomed cockatoo that had peviously been abused, so he did have experience. As a couple, We had had doves and cockatiels but the books suggested the TAG for the less advanced bird person. I have kids. Birds take about as much attention if you're going to do it right, I believe. Get what you're ready for and be honest with yourself, so the bird isn't the one to suffer in the end.... i.e. being a rehome. Make sure you have spent some actual hands on time so you know what you're in for (all birds bite at one time or another, even if they are the nicest bird EVER!~) GOOD LUCK!~
