I had to go with hearing. Although I have heard, that hearing can be more difficult to be without. The thought being, that it makes it more difficult to communicate, and those who have lost hearing become paranoid, and left out of the conversation. But without sight, I would have difficulty working at anything close to what I am good at now. Hearing would certainly be a hindrance, but without site, programming would be tough, and I don't think that it is good to find your way around an electrical cabinet by touch.
