I am new to the community, not new to the finch love/obsession though

The fact is, I am now living in Japan, starting a new journey, and as soon as I will be stable here I am considering to buy a finch, and I am between Java or Society, not only because they are extremely easy to find here, but also because I want to have as much interaction with it as I can. It´s very strange, but luckily for me in Japan is very normal to find baby birds in the stores (totally impossible in Europe or in the States...), so my idea is buying the youngest baby I can find and hand raise it with lots of love, patience and care. I have a lot of experience in hand raising birds, I used to work in an animal hospital and took care of the nursery where hundreds of wild orphan birds came every week... my doubt is, which of this species, Java or Society, is more easy to be handled/enjoys more human interaction/contact?
As far as I have seen in the forum, Java finches seems to be extremely intelligent, strong and sensitive birds with a lot of personality, while society finches seems to be more easygoing, funny and easier to take care of (?). I am not looking for the easiest, but for the one who can have a happier life if I am interacting every day with him, taking in my hand, maybe touching his head as I have seen society finches doing to each other (is that good for java finches too?)...
I apologize if my english sounds strange, I am spanish

Thank you in advance, I will appreaciate all information you can give me about this topic!
