I much prefer bare eyed cockatoos, which have a similar look, slightly larger size, and more African grey like intelligence expression of personality. There's three subspecies of those particular birds to pick from.
The goffins I've met in stores have less than impressed me;however, there's been a recent scientific study proving these are highly intelligent birds.
My point is, if you're going by look factor, you have other cockatoo subspecies to choose from. Ultimately it's going to be the personality of the bird overall it's going to make your overall decision, even if you do decide on specific subspecies of cockatoo to only consider.
