What macaw species would you recomend for someone who is expirienced in bird keeping and would like a macaw?

I've had ateils, parakeets, lovebirds, etc. all good birds, knew how to train, feed, and play with them. Now I want a macaw! I think I could handle it, it won't be easy, but I think I could handle. I've known about macaws and how to care for them for years, I literally think I know every tip, piece of advice, and warnings in the book. Just never had one. I heard how Hyacinth Macaws are "gentle giants" and how with training they came become the perfect pet. Would you suggest that, or something like a Scarlet Macaw? It doesn't matter what extra care it needs, I'll be able to provide it with all it needs and more, just need help finding a suitable species for me. I don't believe in locking large adult birds in tiny cages, and I have about three large to medium rooms for them to be kept. One room I would like to place them in is a 12x8 foot room, as well as a partner.
