cape vs african grey?

[Nir]

Just wondering on the difference between these 2 birdies specially from people who had experiences with both. only interested in the general differences that these 2 birds seem to have. i am by no means getting 1 right now. but in the future (probably 5-10 years down the line) i probably will add 1 more bird and no more then that because i dont want to spread my attention to thin. so wondering what the differences are. and so far these 2 birds are what i am interested in.
