Bem vindo,
It's really hard to figure out what to get, specially when, like us, you live in a place where RBs are rare (specially CCRs). My decision was based on the support I could get down here. Dive Rite has a representative, APD does not, yet. I believe both units are capable to do most types of diving.
One issue for the optima is having the ExtendAir down here. It gets expensive to ship. Anyway, I love using extendair!
Good luck with your choice and feel free to ask any more questions.

If it is easy for him to get support maybe if you guys live close to each other when you order EAC you can order more and split the cost and maybe save some money. if not you will at least have someone whom could help you on issues on the o2ptima. By the way I have had mine almost 1 year and about 80 hours on it and love it. So i would say go for the o2pitma and the close support.
Mike
