Most likely vision, because sometimes sound plays a much more important role for me, not image. In a conversation with the help of intonation, it is much easier to understand the intentions of your interlocutor, while the visual effect can deceive!
Even when I get to know each other, I first of all draw it to the voice: its tebr, strength, height and depth.
For me, sounds are something tangible that you can feel with your whole body.
Of course, hearing, because 90% of information we get from sight. I am an artist and it is very important for me to paint. I understand that I will no longer be able to listen to my favorite music, which is also very important for me, but I will be able to watch movies with subtitles, I can walk without a cane, and I can see my beloved wife. That would be enough for me. Otherwise, of course, it would be better if no one took anything from you.
Of course, I would keep my sight - the amount of information is simply incomparable. The most you lose without hearing is the majority of frequencies in music. After all, you can talk with signs, and you can also learn to read lips. Again, no one canceled the reading. And the music ... if it's modern, I think I won't miss it much :-)
I would try to ask why he would take anything from me at all, heh. And so most likely a rumor, because thanks to my vision I get most of the information. It would be better if he called the sense of smell. I have problems with him and getting rid of him is not as offensive as hearing or seeing.
I would give it a rumor. For I paint. And without sight, I can hardly do it. And also without hearing, you can calmly watch TV shows with subwoofers, enjoy the environment, and the sound is easier to reproduce in your head than a picture, it seems to me. So, despite the lack of hearing, I can easily reproduce and hum my favorite songs in my mind)))
